Product description
Product parameters
Reference standard: DL/T596-1996, GB50150-160
Features:
● The power supply capacity is greatly reduced, and the test power supply power is only 1/Q of the test capacity;
● Small size and light weight, generally 1/3-1/5 of the common test equipment;
● The resonant power supply is a resonant filter circuit, which can improve the waveform distortion of the output voltage and obtain a good sinusoidal waveform, effectively preventing the harmonic breakdown of the sample from being accidentally broken.
● Variable frequency power supply protection, strong stability, a variety of working modes, easy to operate. Optional 220V or 380V power supply for convenient on-site power;
● The high-voltage reactor adopts the modular combination, which can be combined and matched to meet the test requirements of various samples, which is convenient for on-site handling.
