Features of this portable DC Hipot Test High Voltage Test
1. Stable Output Current: high-frequency voltage doubler circuit is adopted, and the latest PWM pulse width modulation technology and voltage and current double closed-loop feedback technology are applied to improve the power regulation rate and load regulation rate, so that the voltage stability is high and the ripple is small. Full-scale smooth voltage regulation,high output voltage accuracy. The host voltmeter directly displays the voltage value loaded on the load, without the need for an external voltage divider, and the wiring operation is simple. The voltage resolution is 0.1kV, and the current resolution is 1uA.
2. Comprehensive protection: complete protection functions, including zero-position protection, over-voltage protection, over-current protection, and breakdown protection. The protection circuit uses nanosecond-level special sensors, which operate quickly and reliably, effectively ensuring personal and equipment safety.
3. 75U function: add a smart high-precision 0.75U function one-key button, press this button, the voltage and current automatically jump to 0.75U state, which is conducive to the testing of zinc oxide arresters.
4. Zero-start boost: The boost potentiometer is zero-start boost, using imported multi-turn potentiometer, the boost process is stable and the adjustment accuracy is high.
5. Overvoltage setting: digital dial switch is used for overvoltage setting, which is easy to operate and has high setting accuracy.
6. Integrated design: The integrated design is adopted, and the host and the pressure doubler are placed in one chassis. Imported high-frequency high-voltage rectifier diodes are selected to make the pressure doubler compact, improve the efficiency of the whole machine, and be easy to carry.
7. Reliable performance: high-performance imported components are selected for key components, and the surface of the double pressure cylinder is coated with special insulating materials, which have good electrical performance, strong moisture resistance and no leakage.
8. Simple operation: the function buttons of the instrument interface are reasonably arranged, the instructions are clear, and it is easy to learn and use.
