DC hipot tester HZZGF

• Output voltage range: 60kV–300kV (multiple models) • Ripple factor: ≤0.5% • Voltage regulation accuracy: ≤0.1%, measurement accuracy ±0.5% • Current measurement accuracy: ±0.5%, resolution 0.1µA • Working power supply: AC220V ±10%, 50Hz • Protection functions: over-voltage, over-current, short circuit, break line, non-zero potential start • Working condition: 0–40℃, humidity <90%, altitude <3000m The Huazheng DC Hipot Tester adopts PWM high-frequency technology with closed-loop regulation for stable voltage, low ripple, and fast protection. It tolerates direct discharge of large-capacitance equipment and supports smooth adjustment across the range. Dupont solid encapsulated multipliers eliminate the drawbacks of oil or air-filled designs. Its compact, lightweight structure suits lab and field use, and the green backlit LCD provides clear readings in all environments. The device integrates voice prompts and a simple control panel for user-friendly operation. Built-in protections against over-voltage, over-current, short circuit, and non-zero potential start ensure safety. With models from 60kV to 300kV, it meets the needs of utilities, transmission companies, industries, and research institutes. The tester runs continuously at rated load and remains stable under ±10% grid fluctuation. As a reliable DC high-voltage source, it is widely applied in preventive tests, cable experiments, and insulation verification, providing safe, accurate, and efficient solutions.
