ACS-Li Series 1–3kVA Online Rack UPS
ACS-Li Series 1–3kVA Online Rack UPS is a compact rack-mounted lithium UPS designed for servers, network systems, communication equipment, and other critical rack applications requiring clean online power.
Compact rack format: The series provides 1–3kVA capacities in compact rack chassis.
Lithium battery integration: Internal lithium batteries reduce battery footprint, while long-backup versions support external battery systems and adjustable charging.
Full active power: Output power factor of 1.0 provides full usable kW capacity.
Flexible communication: LCD monitoring, RS232, optional USB/SNMP, intelligent slot, EPO, Modbus/RTU and optional RS485 BMS communication support centralized management.
Final selection depends on rack space, AC voltage platform, rated capacity, lithium battery configuration, BMS communication, runtime and project requirements.
