ACS Series 1~3kVA online Tower UPS
ACS Series 1–3kVA Online Tower UPS is a compact single-phase online UPS designed to deliver continuously regulated sine-wave power for servers, network devices, communication systems, and other sensitive equipment.
Full active power: The series covers 1–3kVA with output power factor 1.0.
Wide input range: The UPS operates from 110–300Vac, with 176–264Vac at full load.
Flexible backup options: Standard models use internal sealed VRLA batteries, while long-backup versions support external battery packs and adjustable charging.
Intelligent monitoring: LCD, RS232, optional USB/SNMP, EPO and optional BMS communication support local and remote management.
Final selection depends on rated capacity, standard or long-backup design, battery voltage, required runtime, outlet type and project requirements.
