Key Features

• Double-conversion online design: The UPS continuously rebuilds the power your devices receive, so they run on a clean, regulated supply rather than raw mains.

• 1KVA / 1KW rated capacity: There is enough headroom to back up a desktop setup, networking gear and similar small loads.

• Wide input voltage range (110-300VAC): It tolerates heavy undervoltage and overvoltage, so it falls back on the battery less often.

• DSP digital control: Digital signal processing helps keep output regulation precise and responsive.

• Active power factor correction (PFC): It draws power from the mains more efficiently, which makes better use of the available supply.

• Cold start from battery: You can switch the UPS on from its batteries even when no mains power is present, which helps during an outage.

• Segment display with 4 buttons and 4 LEDs: You can check operating mode, load and input/output status at a glance without guessing.

• Low noise (≤45 dB): It is quiet enough to sit beside a desk or workstation without being distracting.

• Overload tolerance: It handles short overload periods on both mains and battery, giving you time to reduce the load.

• Selectable output voltage (208/220/230/240VAC): The same unit can be matched to your local supply standard.
