Product Features
The product is small in size and light in weight, making it easy to quickly assemble and use on site.
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 shall not exceed 65K.
Wide frequency modulation range and low partial discharge.
There is no transient overvoltage after the sample flashover.
Adopting a computer-controlled measurement system, it is easy to operate, has strong anti-interference ability, and has good output stability.
Fiber-optic communication is adopted to ensure personal and equipment safety.
