Military Fiel-Grade Inverter

SynQor’s Military Field-Grade Inverter units are designed for the extreme environmental and demanding electrical conditions of Military/Aerospace applications. SynQor’s MINV incorporates field proven high efficiency designs and rugged packaging technologies. This MINV will accept a DC input voltage while delivering a well-conditioned AC output to the load. It is designed and manufactured in SynQor’s USA facilities to comply with a wide range of military standards. Options include a selection of output voltage amplitudes, frequencies, and an electronic breaker on the AC output to permit fault-tolerant parallel operation for higher power and/or N+M redundant systems.

Helios Power Solutions is Synqor authorized distributor in Australia, New Zealand, Saudi Arabia, Oman, Jordan, UAE, Qatar and Bahrain.
