700VA / 420W UPS Power Protection

The Eaton 3P Ellipse 700 USB IEC is rated at:

700VA / 420W

These two numbers describe different aspects of UPS capacity.

What Does 700VA Mean?

VA, or volt-amperes, measures apparent electrical power.

The 3P700UI has a maximum apparent power rating of:

700VA

What Does 420W Mean?

Watts describe the active power that connected equipment actually consumes.

The maximum active output capacity of this UPS is:

420W

Connected equipment should therefore remain within both the 700VA and 420W limits.

Do Not Size a UPS Using VA Alone

A device may have a 700VA rating but that does not mean it can continuously supply 700 watts.

For the Eaton 3P700UI, the critical maximum active-power figure is:

420W

When selecting a UPS, allow sensible capacity headroom rather than operating continuously at its maximum limit.

Designed for PCs, Networking and Office Equipment

The 3P Ellipse 700 USB is designed for residential and small-business power protection.

Typical suitable equipment can include:

• Desktop PCs
• Small workstations within the 420W load limit
• Computer monitors
• Broadband routers
• Wi-Fi equipment
• Network switches
• NAS devices
• Small office IT equipment
• Point-of-sale systems
• Home-office electronics
• Selected entertainment electronics

Three Battery-Backed IEC C13 Outlets

The 3P700UI provides:

3 × IEC C13 outputs with battery backup and surge protection.

Equipment connected to these three outputs can continue receiving power temporarily when the mains supply fails, subject to the connected load and available battery charge.

What Should Be Connected to the Battery-Backed Outlets?

Use the battery-supported outlets for the equipment that needs enough runtime to continue operating briefly or shut down safely, such as:

• Desktop computer
• NAS
• Router
• Network switch
• Essential communications equipment

One Surge-Only IEC C13 Outlet

The fourth IEC C13 outlet provides:

Surge protection without battery backup.

This is useful for peripheral equipment that benefits from surge protection but does not need to remain powered during a blackout.

Surge-Only Does Not Provide Runtime

If mains power fails, equipment connected to the surge-only C13 socket will switch off.

Only the three battery-backed C13 outputs provide temporary battery power during an outage.

IEC C13 / C14 Connectivity

This exact 3P700UI model is the IEC version of the Eaton 3P Ellipse 700 USB.

It uses:

• Input: IEC C14
• Outputs: 4 × IEC C13

This makes it particularly suitable for conventional computer and IT equipment using IEC power connections.

Two IEC-to-IEC Cables Included

Eaton lists the package contents as including:

2 × IEC-to-IEC equipment cables

along with the USB communication cable, quick-start information and safety instructions.

Built-In Surge Protection

The Eaton 3P Ellipse incorporates dedicated surge protection designed to protect connected equipment from potentially damaging transient overvoltages.

Eaton states that the 3P Ellipse's surge-protection system complies with:

IEC 61643-11

Why Surge Protection Matters

Electrical surges can be caused by events including:

• Utility-grid switching
• Power restoration after an outage
• Large electrical loads switching
• Electrical disturbances within a building
• External power events

A UPS cannot guarantee protection against every possible electrical event, but integrated surge protection adds another layer of defence for connected electronics.

Offline / Standby UPS Topology

Eaton officially classifies the 3P700UI topology as:

Offline

This is also commonly described as a standby UPS.

How a Standby UPS Works

During normal operation, connected equipment receives mains power through the UPS.

If the incoming mains supply moves outside the UPS's acceptable operating conditions or fails completely, the UPS transfers the supported battery-backed outlets to battery power.

Not a Line-Interactive AVR UPS

The 3P Ellipse 700 USB should not be described as a line-interactive UPS.

Eaton specifically identifies the topology as Offline.

If your application specifically requires automatic voltage regulation / AVR without transferring to battery, choose an appropriate Eaton line-interactive UPS instead.

230V Output for UK and European IT Equipment

The UPS operates at a default nominal output of:

230V AC

Eaton lists configurable nominal voltage options of:

• 220V
• 230V
• 240V

Wide Input Voltage Acceptance

Eaton specifies a normal input voltage range of:

184V to 264V

with an adjustable operating range extending to approximately:

161V to 284V

This allows the UPS to accommodate a range of mains conditions according to its configured operating settings.

50 / 60Hz Operation

The 3P700UI supports nominal mains frequencies of:

• 50Hz
• 60Hz

Eaton currently specifies an input operating frequency range of approximately:

46Hz to 70Hz

Replaceable 12V 7Ah Battery

The Eaton 3P Ellipse 700 USB contains:

1 × 12V / 7Ah sealed lead-acid battery

User-Replaceable Battery Design

The internal battery is replaceable rather than permanently sealed into the UPS for its entire service life.

This can help extend the useful life of the UPS because a worn battery can be replaced without replacing the complete UPS electronics.

Sealed Lead-Acid Battery Technology

Eaton identifies the internal battery chemistry as:

Sealed lead-acid / SLA

This is a widely used rechargeable battery technology in UPS systems because it provides reliable standby energy storage and established replacement options.

Approximately 8.5 Minutes Runtime at Half Load

Eaton specifies approximately:

8.5 minutes runtime at half load.

Half load is approximately:

210W

because the UPS has a 420W maximum active-power rating.

Runtime Depends Strongly on Load

Battery runtime is not fixed.

A lightly loaded UPS can run substantially longer than one operating near its maximum power rating.

Approximately 1.5 Minutes at Full Load

At the full rated load of approximately 420W, Eaton lists battery runtime of around:

1.5 minutes

This illustrates why a UPS should be sized for the actual connected equipment rather than simply assuming a fixed number of backup minutes.

Why Full-Load Runtime Is Shorter

The faster connected equipment consumes stored battery energy, the less time the battery can maintain the load.

Typical runtime is affected by:

• Connected wattage
• Battery age
• Battery state of charge
• Ambient temperature
• Individual equipment behaviour
• UPS configuration

Cold-Start Capability

The 3P700UI supports cold start.

This allows supported battery-backed equipment to be powered from the UPS battery even when normal mains power is unavailable, subject to available battery charge and load limits.

Automatic Battery Testing

Eaton includes an automatic battery-test function to help monitor whether the internal battery can continue providing backup power.

Battery testing can help identify ageing or deteriorating batteries before an unexpected mains failure occurs.

Deep-Discharge Protection

The UPS includes deep-discharge protection.

This battery-management feature helps protect the internal battery from excessive discharge that could otherwise shorten its service life.

Constant Battery Recharge

During normal mains operation, the UPS maintains the internal battery so stored energy is available when an outage occurs.

Like all rechargeable batteries, the internal SLA pack naturally ages and will eventually require replacement.

USB Communication for PC Shutdown

The USB version of the 3P Ellipse includes a dedicated:

HID-compliant USB communication port

A USB cable is supplied with the UPS.

Why USB Communication Matters

Connecting the UPS to a supported computer allows the operating system or Eaton software to receive UPS status information.

This can enable automated actions when mains power fails, including:

• Monitoring UPS status
• Detecting a power outage
• Monitoring remaining battery condition
• Triggering automatic computer shutdown
• Reducing the risk of an uncontrolled system shutdown

Automatic Shutdown Support

Eaton specifically lists an:

Auto shutdown function

for the 3P700UI.

This can be particularly valuable when a computer is unattended during an extended power outage.

Eaton UPS Companion Software

The 3P700UI is compatible with Eaton UPS Companion.

Eaton states that the software can provide functionality including:

• Safe computer shutdown
• UPS configuration
• Energy-use monitoring
• UPS status information

HID-Compliant USB Integration

The UPS uses a standard HID-compliant USB connection.

Eaton highlights integration with major operating-system environments including:

• Windows
• macOS
• Linux

Exact software functionality can depend on the operating system and currently supported Eaton software version.

Two USB Charging Ports

In addition to its USB communication interface, the 3P Ellipse USB design includes:

2 USB charging ports

Eaton's current 3P Ellipse platform uses USB-A and USB-C charging connectivity, allowing compatible mobile devices and accessories to be charged conveniently from the UPS.

USB Charging vs USB Communication

These functions should not be confused.

• USB charging ports: designed to supply power to compatible mobile devices.
• HID USB communication port: connects the UPS to a computer for monitoring and shutdown control.

Optional Cloud Monitoring

The 3P700UI includes an expansion slot compatible with Eaton's optional cloud connectivity solution.

When equipped with the appropriate optional CLOUD-PS card, the 3P Ellipse platform can provide remote UPS monitoring.

Remote Status and Notifications

Eaton describes optional cloud connectivity as providing real-time access to:

• UPS status
• Power events
• Notifications
• Remote monitoring information

through compatible web-browser and mobile interfaces.

Cloud Card Not Included

The optional cloud/network card is not supplied as standard with the 3P700UI.

The UPS itself also does not contain a standard built-in Ethernet interface.

Quiet Operation Below 25dB

Eaton specifies an operating noise level of:

less than 25dB at one metre

This makes the 3P Ellipse particularly suitable for equipment located close to the user.

Suitable for Noise-Sensitive Environments

Typical installations can include:

• Home offices
• Bedrooms used as workspaces
• Small offices
• Reception areas
• Retail counters
• Quiet IT workspaces

97% Efficiency at Maximum Load

Eaton lists efficiency at maximum load as approximately:

97%

Higher normal-mode efficiency helps minimise energy lost inside the UPS during everyday operation.

Compact Extra-Flat Design

One of the distinguishing characteristics of the Eaton 3P Ellipse family is its slim chassis.

The exact 3P700UI dimensions are:

• Depth: 235mm
• Width: 81mm
• Height: 263mm

Overall:

235 × 81 × 263mm

Only 81mm Wide

The narrow profile helps the UPS fit beside a desk, PC, cabinet or other equipment without requiring the footprint of a conventional wide tower UPS.

3.9kg Product Weight

Eaton specifies the weight of the 3P700UI as approximately:

3.9kg

A large proportion of UPS weight comes from the internal sealed lead-acid battery.

Flexible Placement

Eaton designs the 3P Ellipse family for flexible installation in office and residential environments.

The slim enclosure can be positioned to suit available space, while optional mounting accessories are available within the 3P Ellipse platform for specialised installations.

LED User Interface

The 3P700UI uses an LED user interface for local UPS status indication.

This provides straightforward visual information without requiring a large integrated LCD screen.

No Built-In Ethernet Interface

The standard 3P700UI does not contain an integrated Ethernet management interface.

Standard communications are provided through:

USB HID

while network/cloud monitoring requires the appropriate optional expansion solution.

Operating Temperature

Eaton specifies the UPS for an operating environment of:

0°C to 40°C

Keep UPS Batteries Away from Excessive Heat

Although the UPS is rated for operation up to 40°C, battery life can be affected by sustained high temperatures.

For best long-term reliability, position the UPS in a ventilated indoor environment away from excessive heat sources.

Operating Humidity

The specified relative-humidity range is:

0% to 95% non-condensing

The UPS should not be operated where condensation or liquid exposure can occur.

Operating Altitude

Eaton lists operating altitude up to:

3000 metres

Suitable for Home Office Power Protection

A home-office computer can lose unsaved work immediately when mains power fails.

The Eaton 3P Ellipse can provide temporary backup power for a compatible PC and associated networking equipment, allowing the user to save work and shut the system down safely.

Suitable for Broadband Routers and Networks

Low-power networking equipment can be particularly well suited to UPS backup because its electrical load is usually much lower than a desktop gaming PC.

Suitable devices can include:

• Broadband routers
• ONTs
• Wi-Fi access points
• Small Ethernet switches
• Selected NAS units

Actual runtime depends on the combined wattage of connected equipment.

Suitable for Point-of-Sale Systems

Eaton highlights the 3P Ellipse 700 USB for applications such as retail point-of-sale environments.

A short power interruption that shuts down a POS computer or supporting network hardware can interrupt transactions.

UPS backup can provide time for equipment to ride through a brief interruption or perform an orderly shutdown.

Suitable for Small Businesses

Potential small-business uses include:

• Office PCs
• Reception computers
• Retail terminals
• Network equipment
• Small NAS appliances
• Communications equipment
• Home-based business systems

Not a Generator or Long-Duration Power Source

The 3P700UI is designed primarily to provide short-term battery backup and allow connected equipment to continue operating briefly or shut down safely.

It should not be treated as a replacement for a generator or large-capacity energy-storage system when hours of backup are required.

Not Designed to Power More Than 420W

The connected battery-backed load must remain within the UPS's:

420W maximum active-power rating.

Always check the actual electrical demand of the equipment before connecting it.

Runtime Falls as Load Increases

Eaton's ratings illustrate the relationship clearly:

• Approximately 8.5 minutes: half load
• Approximately 1.5 minutes: full load

Runtime can vary due to battery age, battery charge, ambient temperature and the behaviour of the connected equipment.

Automatic Protection for Unattended Computers

One of the main advantages of choosing the USB version rather than the basic 700VA Ellipse model is communication capability.

A connected computer can receive UPS information through the HID USB interface and use supported software to initiate a controlled shutdown before the battery becomes depleted.

Battery Can Be Replaced Instead of the Whole UPS

UPS batteries are consumable components whose usable capacity declines with age and cycling.

The 3P Ellipse is specifically designed with a replaceable battery, helping extend the service life of the main UPS electronics.

Signs a UPS Battery May Need Replacement

Battery replacement may eventually be required if:

• Backup runtime becomes unusually short
• The battery fails a UPS self-test
• The UPS reports a battery condition warning
• The unit can no longer sustain a previously supported load
• The installed battery has reached the end of its recommended service life
