JUNXY-380V-120KVA-1P AC Power Source

IGBT/PWM Principle

It is a machine that takes electrical input power at one frequency and voltage and provides variable output voltage and frequency for testing loads over their full voltage and frequency. Solid state units convert in coming AC power into DC power, and then convert the DC into the required output power. Its design is based on advanced DSP and high frequency PWM(pulse width modulation) technology. By employing the IGBT module to reduce circuit complexity, and crystal oscillation to enhance frequency stability. Full galvanically isolated provides pure sine wave output and no harmonic distortion. Totally makes the unit with accurate regulations and no minimum distortion which are very suitable to be a standard AC power source for EMI/EMC/life and safety test.
