ACS Series 6–20kVA Single-Phase Tower UPS is an online double-conversion power system developed for reliable protection of servers, network equipment, industrial control systems, and other critical single-phase loads.
Flexible model range: The tower family covers 6–20kVA, with standard-backup 6/10kVA models and long-backup configurations for extended runtime.
Full active power: An output power factor of 1.0 allows the rated kVA capacity to be delivered as usable kW output.
Efficient power protection: Online efficiency reaches up to 95.5%, ECO mode reaches up to 98%, and input power factor is above 0.99.
Intelligent management: DSP control, LCD and LED monitoring, intelligent battery management, RS232, RS485, EPO, optional USB, SNMP, dry contacts, and parallel communication support local and remote operation.
Final model selection depends on rated capacity, input arrangement, standard or long-backup design, battery quantity, charger current, parallel requirements, and project conditions.
