Core specifications at a glance

Online protection for sensitive equipment

Double-conversion technology continuously converts incoming power before supplying connected devices. This helps maintain a consistent supply for sensitive IT equipment. The sine wave output is suited to equipment that needs clean AC power.

The UPS also provides Emergency Power Off and automatic restart. ECO mode offers an alternative operating mode, while audible alarms alert you when it runs on battery or needs battery replacement.

Runtime and battery management

At a typical half load, the UPS provides 21 minutes of backup. At full load, expect around eight minutes. Actual runtime depends on the connected load.

The sealed lead-acid battery is hot-swappable, so you can replace it without powering down the UPS. Automatic battery testing helps monitor battery condition, and a full recharge takes around three hours.

Monitoring and installation options

Use the USB connection or RJ-45 serial interface to connect the UPS for monitoring. Its SmartSlot supports an optional Network Management Card. With the relevant card and PowerChute Network Shutdown, it can support graceful shutdown for physical servers, virtual machines and HCI clusters.

This model can be installed as a tower or in a rack, where it occupies 2U. A rail kit is not included. Active cooling uses a built-in fan, and the stated noise level is 50dB.
