Pure Sinewave Three-phase 400 Hz DC-AC Inverters
The NGLM series accepts 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 most popular 6KVA chassis measures only 17.75”L x 13”W x 8”H and weighs just 34 pounds. 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.
