LSCDP Series Intelligent Ultra-Low Frequency AC Withstand Voltage Test Device
Darui Electric recommends
Product Features
★ Current and voltage data are directly sampled from the high-voltage side, ensuring real and accurate data.
★Overvoltage protection: When the output exceeds the set voltage limit, the instrument will shut down for protection, with an action time of less than 20ms.
★Overcurrent protection: Designed with dual protection for both high and low voltage sides. The high-voltage side can be precisely shut down according to the set value; the low-voltage side will shut down when the current exceeds the rated current, with an action time of less than 20ms.
★The high-voltage output protection resistor is designed inside the boost unit, so no external protection resistor is needed.
★Due to the use of a high-low voltage closed-loop negative feedback control circuit, there is no capacitive rise effect in the output.
