The NGLRK inverters are intended for industrial and military applications where DC voltage needs to be converted to 50 Hz, 60 Hz or 400 Hz, 3Ø. These inverters are used for running electronic loads such as computers, monitors, printers, telecom systems and radios from 24-270 VDC derived from batteries and field generators. They can also be used for hand tools & motors. These units can be further ruggedized for military grade shock, vibration, temperature and humidity. Utilizing field proven technology, this series of rugged pure sinewave DC-AC Inverters is suitable for harsh environments and can be optionally customized for unique sizes and shapes. The output is 4 wire WYE with 3 phases and a neutral line, and these units can work with totally unbalanced 3Ø loads.
