Product Features of Program-controlled Ultra-low Frequency High Voltage Generator

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

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.

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.

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

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

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.
