Wuhan Huayi Electric Power Technology Co.,Ltd

 

DC hipot tester adopts high frequency voltage doubling circuit, using the latest PWM pulse width modulation technology and the voltage and current double closed loop feedback technology to improve the power supply adjustment rate and load regulation rate, make voltage more stable and ripple smaller. Using imported high power IGBT device and its driving technology to eliminate the interference of the switch. According to EMI electromagnetic interference and EMC electromagnetic compatibility theory, shielding, isolation and grounding measures are adopted to improve the safety of the whole machine, and can withstand rated voltage discharge without damage. The selection of imported high-frequency high-voltage rectifier diodes makes the cylinder more compact and lightweight, to enhance the efficiency of the whole machine.

Instrument protection function is complete, with zero protection, over-voltage protection, overcurrent protection, breakdown protection, protection circuit selection of nanosecond special sensor, quick and reliable action, effectively protect the safety of personal and equipment. Add intelligent high-precision 0.75U1mA function button, which is conducive to the test of zinc oxide arrester

 

 

 

 

1. Output voltage stable: Adopts latest PWM pulse width modulation technology and the voltage and current double closed loop feedback technology. The power supply adjustment rate and load regulation rate is improved, with small ripple.
2. Comprehensive protection: completed protection functions, like zero protection, over-voltage protection, over-current protection, breakdown protection, circuit protection, using nanosecond special sensor, fast and reliable action, can effective protect user and equipment safety.
3. 0.75U function: add intelligent high-precision 0.75U function button. With this button, the voltage and current automatically to the 0.75U state, which is conducive to zinc oxide arrester test.
4. Voltage stepping from zero: boost potentiometer zero boost, with multi circle potentiometer, boosting process is stable, high precision adjustment.
5. Over-voltage setting: use digital dial switch, easy to operate, high setting accuracy.
6. Integral design: cylinder and the host are placed in a box. Use imported high-frequency high-voltage rectifier diodes, cylinder  has compact size, portable, easy to carry.
7. Reliable performance: the key components are high performance imported components, the outer surface of the cylinder is coated with special insulation materials, good electrical performance, strong moisture capacity, no leakage.
8. The operation is simple: the instrument interface each function key, the layout is reasonable, the instruction is clear, easy to learn and use
