Product Feature And Application
1. Data of current, voltage, wave form can be directly sampled at high voltage side, so the data is real and accurate.
2. Overvoltage protection: If the output exceeds the set limit of voltage, the instrument will shut-down to protect itself; the actuation time is less than 20ms.
3. Overcorrect protection: it is high-low voltage dual protection in the design, the accurate shut-down protection can be made according to the set value at high voltage side; If the current on low voltage side exceeds the rated current, the instrument will take shut-down protection, the actuation time are both less than 20ms.
4. A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protective resistor connected outside.
5. With the high and low voltage closed-loop negative feedback control circuit, the output is no capacitance rise effect.
6. Small volume, light weight, easy to carry
7. Has the regulator of frequency, can adjust the output frequency to 0.1,0.05 and 0.02 Hz
8. Can meet different requirement of the high voltage tester for cable and electric equipment with different model
