Product Features
This product adopts a continuously adjustable air gap method to change its inductance value, so that the circuit is in a power frequency resonance state.
The output voltage waveform is a sinusoidal waveform with low waveform distortion and low waveform distortion rate.
The input capacity of the power supply is only 1/Q of the output capacity.
Copper winding, low current density, high system quality factor. Under the corresponding load time, the temperature rise of the winding
Not greater than 65K.
The product is small in size and light in weight, making it easy to quickly assemble and use on site.
Adopting high-voltage filtering to reduce overall partial discharge.
Adopting a special adjustment structure, greatly reducing noise levels.
There is no transient overvoltage after the sample flashover.
Adopting a computer-controlled measurement system, it is easy to operate and has strong anti-interference ability.
