ACM Series 50–600kVA Modular UPS
50–600kVA Modular UPS is a scalable online double-conversion power system designed for telecommunications, data processing, industrial control, and other critical loads.
Scalable capacity: 50kVA power modules support system expansion from 50kVA to 600kVA, with flexible capacity and redundancy configurations.
Wide input range: A -40% to +25% input-voltage range, input power factor of 0.99, and THDi of 2% support stable operation.
High efficiency: Online double-conversion efficiency reaches up to 96%, while ECO mode reaches 99%.
Flexible integration: Supports external batteries, RS232, RS485, USB, dry contacts, EPO, optional SNMP monitoring, and optional parallel communication.
Final configuration depends on load capacity, redundancy, battery backup time, cabinet type, cable entry, and project requirements.
