Product Description
50kV VLF Hipot Tester
VLF means 'Very Low Frequency' and 0.1Hz to 0.02Hz is considered to be very low frequency, used as a AC output tester. Although the frequency is very low, it is still an alternating current with polarity reversals every half cycle. At 0.1 Hz output, rather than 60Hz, it takes 600 times less current and power to apply an AC voltage to a capacitive load, like a long cable.

The GDVLF Series of VLF-AC hipots apply the device with a microprocessor controlled, which control voltage automatically, and can also be adjusted manually in the process of automatic voltage boost. Our advanced electronic design is more convenient for you to use VLF hipots available. A big LCD screen and onscreen instruction system can display output Sinusoidal while built-in thermal printer can print the test report, easy to operate.

Features
1. If the output voltage exceeds the limit users set, the instrument is supposed to shut-down itself, react within 20ms;
2. The high-low voltage dual protection exsit in the design, so automatic protection can be made according to the set limit of low and high voltage;
3. If the current on low voltage side exceeds the load current, the instrument is supposed to shut-down itself, react within 20ms;
4. Using high&low voltage closed loop negative feedback control circuit, so there is no capacitive rise effect in the process of output;
5. A high voltage output protective resistor is provided in the voltage boost body, no need to connect resistor outside;
6. Split/Whole equipment as customer's requirement.
