- Details
1. This product is primarily suitable for DC withstand voltage tests on high-voltage electrical equipment such as zinc oxide surge arresters, power cables, transformers, and generators in power, mining, metallurgy, and steel industries.
2. It employs a high-frequency voltage multiplier circuit, utilizing PWM pulse width modulation technology and high-power IGBT devices.
3. It utilizes voltage negative feedback, resulting in high output voltage stability and a low ripple coefficient (≤1%).
4. It features smooth voltage adjustment across the entire range, with fine voltage regulation precision (≤0.5%), stability (≤1%), voltage and current errors of 1% (reading ±0.2kV), and current errors of ±1 digit.
5. It includes a boost potentiometer for zero-start voltage boosting.
Product Features:
75% UDC 1mA function button for convenient zinc oxide surge arrester testing, with an accuracy of 1% (reading ±1%).
Overvoltage protection is set using DIP switches, providing clear indication and an error of ±1%.
The voltage multiplier uses new materials. The exterior is coated with a special insulating material, offering excellent electrical performance and strong moisture resistance.
Foldable support feet with a large diameter area ensure good stability.
