Built for the Field

The Centurion UPS (RMHCPU-20) is ATSI's highest-capacity military uninterruptible power supply, delivering 20 amperes at 28VDC with a seamless, transparent mains-to-battery transition. It accepts two to four Hawk 24V Ni-MH batteries — with four batteries delivering approximately ten hours of runtime at full 20A load — making it capable of sustaining an entire forward operating base power system through extended mains outages. The 25mm ruggedised aluminium construction exceeds standard military enclosure specifications, providing exceptional resistance to impact, vibration, and environmental hazards. Assigned NSN 6130-99-490-4703, the Centurion is fully qualified within the NATO supply chain and documented in four languages for multi-national deployment.

20A@28VDC — Maximum Field UPS Capacity

The Centurion delivers 20 amperes at 28VDC — double the output of the RMHCPU-10 — capable of sustaining multiple critical systems simultaneously through extended mains outages.

🔌

Seamless Mains-to-Battery Transition

Instantaneous and transparent switchover from mains to battery power — connected equipment continues operating without interruption, reset, or loss of state.

🔋

Up to 10 Hours Runtime with 4 Batteries

With four Hawk 24V Ni-MH batteries configured, the Centurion delivers approximately ten hours of runtime at full 20A load. Two batteries provide a lighter, shorter-duration configuration for more mobile deployments.
