Product Description

Product Introduction

Developed exclusively for power engineering, XHZG series DC high voltage tester performs DC voltage withstand and leakage current tests on surge arresters, power cables, transformers, breakers, generators and other high voltage devices. It is essential equipment for power insulation inspection and routine preventive maintenance.

Key Advantages

Equipped with IF voltage multiplier circuit, PWM modulation and high-power IGBT modules for stable and high-efficiency operation.
Advanced voltage feedback design keeps steady output voltage, ripple coefficient controlled within 1%.
Stepless full-range voltage adjustment, test precision up to 0.5% and stability within 1%.
Smooth zero voltage start design plus independent 0.75UDC1mA function button, simple to operate and high in control accuracy.
Easy DIP code overvoltage protection setting with ±1% error, effectively avoiding equipment damage.
