Helios Power,SynQor’s Military-Grade UPS Expansion Battery

Our Military Field-Grade Uninterruptible Power Supply units are designed for the extreme environmental and demanding electrical conditions of Military/Aerospace applications.

This UPS will accept a wide range of input voltage and frequency values 80-265VAC; 47-65Hz while delivering a well-conditioned AC output to the load.

Up to three units can be combined to provide higher power, higher voltage and/or multiple output phases. The use of lithium polymer batteries permits the lowest profile and lowest weight solution in its power class. Options include a dual 500 W or single 2500 W DC output, a DC input rated for military 28 VDC sources, an electronic breaker on the AC output to permit fault-tolerant parallel operation for higher power and/or N+M redundant systems. Options include a DC output and the ability to also draw power from a military standard 28 Vdc input.
