Features
Line-Interactive Power Protection
The Ellipse PRO 850 uses line-interactive technology with Automatic Voltage Regulation to correct under-voltage and over-voltage conditions without constantly switching to battery power, helping preserve battery life while maintaining stable output to connected equipment.
850VA / 510W Capacity
With an output rating of 850VA / 510W, the UPS is suitable for protecting compatible desktop PCs, workstations, network equipment and peripherals during short power interruptions and voltage disturbances.
Four IEC C13 Outlets
Three IEC C13 sockets provide both battery backup and surge protection, while a fourth C13 outlet provides surge protection only. This allows critical devices to remain powered while less essential peripherals receive surge protection without consuming backup runtime.
Real-Time LCD Display
The front LCD provides UPS status information and electrical measurements while also allowing supported operating parameters to be configured directly from the unit.
EcoControl Energy Saving
The EcoControl function can automatically switch off selected peripheral equipment when the main connected device is shut down, helping reduce unnecessary energy consumption.
USB Monitoring and Automatic Shutdown
The HID-compliant USB interface works with Eaton UPS Companion software and supported operating systems to monitor power conditions, configure UPS settings and safely shut down a connected computer during an extended power failure.
Replaceable Battery
The internal sealed lead-acid battery is user replaceable and includes automatic battery testing, deep-discharge protection and cold-start support, helping extend the useful service life of the UPS.
- ELP850IEC is the IEC-output version with four IEC C13 sockets.
- Three outlets provide battery backup plus surge protection; one provides surge protection only.
- The internal battery is a single 12V / 9Ah sealed lead-acid battery.
- Actual backup runtime varies according to connected load, battery condition and operating environment.
