1 Product use

This product is a series of products specially developed for motor and transformer testing. This series of products is suitable for general testing of 380V, 6KV, 10KV motors and transformers. In order to meet the requirements of the adjustable power supply for the no-load, load, locked-rotor and characteristic tests of motors and transformers, the company has also successfully developed a new series of high-voltage full-power, three-speed voltage output inductive voltage regulators in recent years. In order to meet the requirements of the test site forbidding oil and to save the use of the test site, a dry-type air-cooled induction voltage regulator with output switch cabinet function has also been successfully developed recently.

2 Product Features

a. Small no-load current, low total loss, efficiency > 96.5%;

b. The lower limit of the output voltage is small, and the short-term overload capability is strong;

c. Adopt chute, good output voltage smoothness;

d. The output voltage waveform distortion rate is small;

e. Three-stage output voltage regulator, the output power of each stage remains unchanged;

f. It can be equipped with a digital voltage regulator control cabinet, so that the voltage regulator can be automatically controlled according to the test needs;

g. For dry air-cooled products, the voltage regulator is integrated with the output switch cabinet, which is very convenient to use.
