Category: VLF High Voltage Generator

Product Description

Product Features


 1. Current, voltage, and waveform data are all directly sampled from the high-voltage side, ensuring data authenticity and accuracy.


2. Overvoltage Protection: When the output exceeds the set voltage limit, the instrument will shut down for protection, with an action time of less than 20 milliseconds.


3. Overcurrent Protection: Designed with dual protection on both high and low voltage sides; the high-voltage side can perform precise shutdown protection according to the set value.


4. When the current on the low-voltage side exceeds the rated current, shutdown protection will be activated, with an action time of less than 20 milliseconds.


5. The high-voltage output protection resistor is designed inside the voltage booster, so no external protection resistor is needed.


6. Due to the adoption of a closed-loop negative feedback control circuit for both high and low voltages, there is no capacitive rise effect in the output.
