Military Field-Grade 3-Phase Programmable Output Power Supply

The MPPS will accept a wide range of frequencies and 3-Phase inputs and has three programmable DC output voltage options; 0-35 V, 0-55 V and 0-80 V, all up to 4 kW of output power. The power supply also includes an user programmable current limit feature.

 

This power supply is designed to meet the strictest military standards MIL-STD-704F, 1275D, 461F, 1399-300B and 810G. The MPPS also tackles the difficult problem of unbalanced 3-Phase loads on aircraft and ships. MIL-STD-1399-300B requires that all the phase currents be balanced to within ±5% for ships and ±3% for submarines. The MPPS achieves a high degree of input phase current balance while delivering regulated DC power, which makes it compliant to MIL-STD-1399. The power supply has been tested extensively to MIL-STD-810G shock, drop and vibration requirements. The units can operate in harsh environments (rain, sand, salt, high altitude and a wide temperature range: -40 °C to +70 °C).
