moisture resistant DC High Voltage Tester with overvoltage protection

DC high voltage tester

main feature:
    1. Adopt high-frequency voltage doubler circuit, apply PWM pulse width modulation technology and high-power IGBT devices.
    2. Using large voltage feedback, high output voltage stability, and small ripple factor ≤ 1%.
    3. Full-scale smooth voltage regulation, fine voltage regulation, adjustment accuracy ≤ 0.5%, stability ≤ 1%, voltage and current error 1% (reading ±0.2kV, current error ±1 word.
    4. The booster potentiometer has zero boost.
    5. With 75% UDC1mA function button, it is convenient for zinc oxide surge arrester test, accuracy 1% reading ±1%.
    6. The overvoltage protection adopts the code setting, which is clear at a glance, and the error is ±1%.
    7. The double pressure adopts new materials, which are light and strong.
    8. The surface is coated with special insulating materials, with good electrical performance and strong moisture resistance.
    9. Folding support feet, large diameter area, good stability.
