Product Parameters Technical parameters Rated Capacity 80kVA rated voltage 160kV Adjustable inductance range 65~130H Rated frequency 50Hz Rated current 0.5A Adjustable gap range 0~300mm Product Characteristics 1#12289;Due to full compensation of resonant reactive power the power of power supply and equipment is less than 1/10 of the required capacity of the subject (1/Q>10). Small size and light weight with the same capacity large output capacity of the device and small power capacity required cheap convenient and safe to use;
2#12289;Series resonance is actually a current filtering circuit so that the current passing through the subject is basically the fundamental current and the waveform distortion rate (THD) of the output voltage is very small which is superior to all existing ac voltage withstand equipment.
