MD20STA-C UL2231-2 CCID20 RCD AC 20mA DC Leakage Protection RCMU Sensor ZCT for EV Charger

Product Details

This is a zero phase leakage current transfomer that complies with the UL2231-2 standard, and its leakage protection type is CCID20. The AC leakage protection threshold is 15~20mA, and the DC leakage protection threshold is 40×1.414=56.56mA. It also protects against mixed leakage current and high-frequency leakage. When the leakage current in the line reaches the above alarm threshold, it will output a leakage alarm signal (OC gate output). In addition, it has a self-test function, which can be used to determine in real time whether the sensor is in a normal working state. If the sensor fails, the self-test output terminal will not be able to output the self-test feedback signal (Open Collector Output), so this leakage sensor will be safer and more reliable in the field of leakage protection.

This series of products is mainly used in electric vehicle charging piles, photovoltaic power generation and other fields. We are committed to providing simple, safe and reliable leakage protection solutions for the safety of electricity use for the majority of users.
