UM High-Frequency Modular UPS(15/20/25/30/50/100 kVA)

UM modular UPS is a new type of modular UPS based on the online dual-conversion technology, with fully modular design. UM can be smoothly expanded to maximum capacity of 800 kVA and characterized with simple and easy maintenance, significantly improves the low availability issue of traditional UPS systems. UM UPS’s outstanding availability, efficiency, and intelligent design perfectly match customers’ requirements for efficient operation and high flexibility of modern data centers.

Modular Design

  • With full modular design, the power module, bypass module, and control module are all hot swappable, support on-demand capacity expansion, and easy maintenance.


High Reliability

  • Redundant design of control units and auxiliary power, with no single point of failure. 138–485 VAC ultra-wide input voltage range, with no derating from 305–485VAC, linear derating to 40% from 138–305VAC, effectively reduces battery discharge cycles and extends battery life while ensuring uninterrupted power supply to servers.


High Efficiency

  • Efficient operation under low load: In online mode, efficiency reaches 96% at 30% load ratio and 95% at 20% load ratio.
  • With high efficiency at low loads, power modules intelligently switches online and sleep mode under extremely low load conditions, ensures redundancy while further enhances the UPS efficiency.


High Availability

  • High power density, with a single container capacity of up to 300 kVA for a 50 kVA module and 600 kVA for a 100 kVA module.
  • Output power factor is 1. No derating for capacitive and inductive loads with input power factor more than 0.5.
  • Quantity of battery cells is adjustable, allows for flexible configurations, avoids to replace the entire set of batteries in case of a single-cell battery failure, and saves customer maintenance costs.
  • Supports on-demand and smooth expansion, where a 50 kVA module can be expanded to 800 kVA on a single UPS cabinet, effectively reduces initial investment costs.
