Introduction to the Uses of High-Frequency DC High-Voltage Generator;
1. Product Features
① Small size, light weight, beautiful appearance, reliable, easy to operate, and full-featured.
② Pulse train logic array modulation, using high-power IGBT devices, phase fuzzy control, resulting in high output stability, low ripple, and frequency up to 100kHz.
③ Designed for maintenance-free operation, main components are imported from Germany, the United States, and Japan, durable and not afraid of continuous direct short-circuit discharge to ground.
④ High precision, accurate measurement, output voltage adjustment uses a single multi-turn potentiometer, smooth boosting process, high adjustment precision, the instrument has high and low voltage terminals for measuring leakage current, the high-voltage terminal uses a spherical shielded digital meter display, not afraid of discharge impact. Good anti-interference performance, suitable for field use.
⑤ The voltmeter on the control box directly displays the voltage value applied to the load test object, no external voltage divider is needed during use, simple wiring, and convenient operation.
⑥ Negative polarity output, zero start, continuously adjustable, with overvoltage, overcurrent, return-to-zero, grounding protection, disconnection protection and other protective functions, safe operation.
⑦ Has 75% function, bringing great convenience to zinc oxide arrester measurement. This instrument has a 75% voltage switch function on the control box. When the current rises to 1000uA, press the 75% button, then the values displayed on the voltmeter and ammeter are the 75% data. After completion, immediately return the boosting knob to zero, and also return the fine-tuning voltage knob to zero. Then return the 75% button switch to the normal position before conducting other tests.
