Developed for high voltage testing work, the XHZG series DC high voltage testing device performs DC pressure resistance and leakage current experiments on various electrical equipment like zinc oxide arresters, electric power cables, transformers, breakers and generators.

• Utilizes medium frequency voltage multiplication structure, combined with PWM control technology and high-power IGBT electronic components.
• High-efficiency voltage feedback technology realizes stable output voltage performance, and the ripple coefficient is less than or equal to 1%.
• Full-scale stepless voltage regulation design, with testing accuracy up to 0.5% and long-term stability within 1%.
• Supports zero initial voltage increase design and independent 0.75UDC1mA function key, meeting 1% precision requirement.
• Dip switch adjustable overvoltage limit, visual and convenient setting, with a tolerance range of ±1%.
