Lab Equipment Ac High Voltage Test Set 50kv Vlf With Ultra Low Frequency

50KV AC Hipot Tester VLF Ultra-Low Frequency High Voltage Generator Lab Equipment

Application:

VLF insulation withstand voltage test is an alternative test method for the power frequency withstand voltage test.The test procedure is greatly reduced, which is more advantageous than the power frequency test. It can be widely used in the AC withstand voltage test of cables, large high voltage rotary motors and power capacitors.This product combines the advanced technology of modern digital frequency conversion, adopts microcomputer control, step-up, step-down, measurement, protection fully automatic, and can perform manual intervention in the automatic promotion process. Because of the full electronic, the volume small weight light, large screen liquid crystal display, clear and intuitive, and can display the output waveform, print output test report. In addition, the following features need to be specified:

Product Features:

1. No need to connect extra protection reactor because of high voltage protection reactor inside booster.
2. Over-current protection:double protection for high and low voltage, stop running accuracy protect high voltage according to set parameter, stop running when low voltage current over rated current, time <20ms.
3.Due to use high and low voltage closed loop control circuit, output without capacitive rise effect.

4. Real and accuracy test results of current, voltage, waveform directly get from high voltage lateral sampling.
5.Over-voltage protection: device stop running when output over setting max voltage, time <20ms.
