Nova Electric's new rugged NGLM-Series Three-Phase Output Pure Sinewave DC-AC Inverters are extremely reliable, designed to provide many years of service in high shock, vibration, humidity, and EMI environments in compliance to RTCA/DO-160G and MIL-STD-704F. These units accept standard inputs of 28, 48, 120, or 230 Volts DC nominal. They are offered in 3KVA, 4.5KVA and 6KVA output power, and output voltage is tightly regulated with less than 3% total harmonic distortion. The NGLM units are modular, with small footprints and flexible mounting configurations. The chassis measures only 17.75"L x 13"W x 8"H and weighs just 34 pounds total. A mounting plate is integrated into the chassis. Input connection is typically via bus bars with terminal blocks for output, though circular MS-type connectors are available optionally. These inverters use field–proven, cutting edge IGBT-based high frequency switching technology to achieve very high MTBF, and very low mean time to repair. Typical applications include military and commercial aircraft.
