Cable AC Withstand Voltage Test Tester/Ultra Low Frequency High Voltage Generator
Product Overview:
This product combines the digital frequency conversion technology, the use of microcomputer control, boost, buck, measurement, protection automation. Because of electronization, so small volume and light weight, large screen LCD display, clear and intuitive, and can display output waveform, print test report. The product design indicators in line with the "special test instruments for power equipment general technical conditions, part 4: ultra low frequency high voltage generator general technical conditions" power industry standards, easy to use.
Product features:
1. The rated voltage is less than or equal to 50kV of the ultra-low frequency single structure (a booster); More than 50kV ultra low frequency series structure (two booster series), so that the overall weight is greatly reduced, with load capacity enhanced, and two booster can be used separately for low voltage level ultra low frequency.
2. The current, voltage and waveform data are directly sampled from the high voltage side, so the data are accurate
3. With over-voltage protection function, when the output exceeds the set voltage limit value, the instrument will stop protection, the operation time is less than 20ms.
4. With over-current protection function: designed for high and low voltage dual protection, high voltage side can be stopped according to the set value protection; When the current of the low voltage side exceeds the rated current, the shutdown protection will be carried out, and the operation time is less than 20ms.
5. The high voltage output protection resistor is designed in the boost body, so there is no need for another protection resistance outside.
6. Because of the use of high and low voltage closed-loop negative feedback control circuit, the output has no capacity rise effect.
