UPS - Military Field-Grade

Field proven, Military Field-Grade, Rugged Uninterruptible Power Supply

SynQor’s family of Field-Grade UPS is designed for the extreme environmental and demanding electrical conditions of Military/Avionics applications. SynQor’s Military UPS Systems incorporate field proven high efficiency designs and rugged packaging technologies. This UPS will accept a wide range of input voltage and frequency values while delivering a well-conditioned AC output to the load. Its use of lithium polymer batteries permits the lowest profile and lowest weight solution in its power class. It is designed and manufactured to comply with a wide range of military standards. Options include a DC output and the ability to also draw power from a military standard 28 Vdc input.
