ZGF-60kV2mA DC High Voltage Tester

Model: ZGF 60kV5mA  DC High Voltage Tester

Application:

This instrument is applicable to sectors such as power, railway, chemical industry, industrial and mining, metallurgy, and steel. It is used for DC withstand voltage tests and leakage tests on equipment like zinc oxide arresters, magnetically blown arresters, power cables, transformers, generators, etc. It can also serve as a power source for electrostatic dust collection, spraying, etc.

Features:

1. Stable Output Voltage: It adopts a high-frequency voltage doubling circuit and applies the new PWM (Pulse Width Modulation) technology and the dual closed-loop feedback technology for voltage and current. This effectively enhances the power supply regulation rate and the load regulation rate, ensuring high voltage stability and low ripple. Smooth voltage regulation is available across the full range, with high output voltage accuracy. The voltmeter on the main unit directly shows the voltage value applied to the load, eliminating the need for an external voltage divider, which simplifies the wiring operation. The voltage resolution is 0.1 kV, and the current resolution is 1 μA.

2. Comprehensive Protection: Equipped with a complete set of protection functions, including zero-position protection, overvoltage protection, overcurrent protection, and breakdown protection. The protection circuit uses a nanosecond-level dedicated sensor, which can act quickly and reliably, providing effective protection for the safety of personnel and equipment.

3. 0.75U Function: An intelligent and high-precision one-touch button for the 0.75U function is added. When this button is pressed, the voltage and current will automatically switch to the 0.75U state, which is highly beneficial for the testing of zinc oxide arresters.

4. Zero-start Voltage Rise: The voltage rise starts from zero via the voltage rise potentiometer. An imported multi-turn potentiometer is used, ensuring a smooth voltage rise process and high adjustment accuracy.

5. Overvoltage Setting: A digital dial switch is selected for overvoltage setting, which is simple to operate and features high setting accuracy.

6. Integrated Design: An integrated design solution is adopted, with the main unit and the voltage doubling cylinder housed in one chassis. Imported high-frequency high-voltage rectifier diodes are used, making the voltage doubling cylinder compact in size, improving the overall efficiency of the device, and facilitating portability.

7. Reliable Performance: High-performance imported components are chosen for key devices. The surface of the voltage doubling cylinder is coated with a special insulating material, endowing it with good electrical performance, strong moisture resistance, and no leakage.

8. Simple Operation: The function buttons on the instrument interface are rationally arranged with clear indications, making it easy to learn and operate.
