ACS-LV Series 1–3kVA Online UPS provides continuous, regulated sine-wave power for servers, network equipment, workstations and other critical single-phase loads.
True power: Output power factor 1.0, delivering 1kW, 2kW and 3kW from the 1kVA, 2kVA and 3kVA models.
120V applications: Selectable 100/110/115/120Vac output supports low-voltage power environments.
Flexible installation: Tower and rack configurations are available for different IT and equipment layouts.
Flexible battery: Standard and long-backup models support different runtime requirements, with charging current up to 8A for long-backup configurations.
Smart monitoring: LCD status display with RS232 and intelligent slot, plus optional communication interfaces for UPS management.
