ACM Series 50–600kVA Modular UPS

Product Overview

ACM Series 50–600kVA Modular UPS is a scalable online double-conversion UPS designed for data centers, telecommunications, industrial facilities, and other mission-critical applications.

Scalable architecture: 50kVApower modules support flexible system expansion up to 600kVAwith configurable redundancy.

Wide input tolerance: -40% to +25%input voltage range, input power factor up to 0.99, and THDi 2%.

High efficiency:Up to 96%online double-conversion efficiency and up to 99% in ECO mode.

Flexible battery options:Supports external VRLA or lithium battery systems according to project requirements.

Smart communication:Supports RS232, RS485, USB, EPO, dry-contact I/O, and optional parallel communication ports.

Configuration Note: Final system configuration depends on cabinet selection, installed module quantity, redundancy level, battery system, communication options, and project electrical design.
