ACT Series 10–40kVA Three-Phase Tower UPS
ACT Series 10–40kVA Three-Phase Tower UPS is an online double-conversion system designed to provide stable, uninterrupted power for critical commercial and industrial loads.
Integrated battery options: The series supports 10/15/20/30/40kVA capacities, with internal 7Ah or 9Ah battery configurations for compact standard-backup installations.
High-efficiency protection: Online efficiency reaches up to 96%, ECO efficiency exceeds 99%, and the output power factor is 1.0.
Reliable power quality: Input power factor is above 0.99, input THDi is below 3%, and synchronized bypass transfer is completed with 0 ms interruption.
Intelligent management: The LCD touch screen, RS232, RS485, USB, dry contacts, EPO, optional SNMP, and optional four-unit parallel operation support local control and centralized monitoring.
Final selection depends on load capacity, internal battery quantity, required backup time, charging settings, redundancy, and project configuration.
