Darui Electric recommends this product for you
Product Features
1. This intelligent DC high voltage generator features an LCD display and has the function of printing test data. The equipment is easy to operate, fully functional, and suitable for field construction. It is an ideal intelligent DC high voltage generator.
2. It is manufactured with professional technology and processes, applying PWM variable frequency pulse width modulation technology, using high-power IGBT devices, and utilizing frequency conversion technology to increase the frequency to 40kHz, thereby making the output high voltage stable and the ripple coefficient small.
3. High precision and accurate measurement. Both voltage and current are digitally displayed, with a voltage resolution of 0.1kV and a current resolution of 0.1uA. The voltmeter on the control box directly displays the voltage value applied to the load test object, so no external voltage divider is needed, and wiring is simple. The instrument has the ability to measure leakage current at both high and low voltage ends. The high voltage end uses a circular shielded digital meter for display, which is not afraid of discharge impact, has good anti-interference performance, and is suitable for on-site use.
4. High voltage adjustment stability, smooth voltage regulation across the full range. The output voltage adjustment uses a single multi-turn potentiometer, the boosting process is stable, the adjustment accuracy is high, and coarse and fine adjustment functions are designed. The voltage adjustment degree is better than 0.1%, the voltage and current measurement error is less than 1.0%, and the ripple factor is better than 0.5%.
5. Negative polarity output, zero start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, zero return, grounding protection, and special disconnection protection. The automatic protection circuit has strong functions, complete and reliable protection, making operation safe.
The medium frequency DC high voltage generator adopts a high-frequency voltage doubling circuit, applies PWM variable frequency technology, closed-loop adjustment, and large voltage feedback, greatly improving voltage stability. This instrument is designed and manufactured according to the requirements of the industry standard ZBF24003-90 "General Technical Conditions for Portable DC High Voltage Generators". It is suitable for DC high voltage testing of zinc oxide arresters, power cables, generators, transformers, switches, and other equipment in power departments, factories and mines, scientific research units, railways, chemical industries, power plants, etc.
