400HZ variable-frequency power is a power equipment with structure of AC-DC-AC, adopted latest SPWM and IGBT inverter technology, which changes the electrical supply into the required voltage and frequency through power converting circuit. It is specially used for aviation and military electric equipment, such as airplane and its carried equipments, radar, navigation, and so on. The adjustment of voltage and frequency range is ±20%, and widely used for laboratory and product line as debugging power supply. 
●Adopting AC parallel redundant technology makes two or more inverted power supply output in parallel mode and enhances system reliability. when one equipment is faulty, it will not affect the normal power supply of the others. Advanced flow equalization technology makes each power supply share the same loading, to extend the power supply capacity and power lifespan.
●Adopting three-phase independently adjustable technology, which can takes 100%unbalance load
●Adopting double frequency inverter technology, which works in the lower frequency, greatly reduce heating power and improve reliability. At the same time, the filter parameter and volume is decreased greatly, enhance peed of response, output stability and precision.
