1 Product use

This product is a voltage regulating power supply specially developed for high-voltage test equipment. It is used for the primary side voltage regulation of UHV test transformers, and is widely used in the test and research of high-voltage electrical appliances and their materials.

2 Product performance

a. Small no-load current, low total loss and high efficiency;

b. The contact system is reliable and spark-free, and the output voltage can be adjusted smoothly, steplessly and continuously;

c. The lower limit of the output voltage is small, which greatly improves the safety of use;

d. The impedance voltage is low, which can meet the requirements of high voltage test (such as pollution test);

e. The output voltage waveform has a small distortion rate and is in the same phase as the input voltage;

f. The product has low noise;

g. It can be equipped with a digital voltage regulating control cabinet, so that the voltage regulator can realize automatic control;
