Product Details
MD0630T41A-1 is an AC DC leakage current sensor (residual current monitoring) for EV charging station. It has the characteristics of high sensitivity, correct measurement, small size and compact/integration design. The residual current monitor can be set separately for AC and DC leakage. When leakage current is detected, an alarm signal is generated, and the switch control signal is output at the same time. The RCD sensor is connected in series with the AC supply to an EV and will provide a signal output if a DC current ≥ 6mA DC flows in the circuit. It can monitor DC (6mA) and AC (30mA) residual currents, and will signal to the Smart EVSE if a fault occurs.
To satisfy new standards including IEC 62752, IEC 62955, IEC 61851-1 etc, the charging of electrical vehicles requires residual current sensors to avoid hazardous situations in cases where the vehicle battery (DC) is connected to the home power supply (AC). This is new type of Fluxgate Current Sensor; it's based on the principle of magnetic modulation. It can be used to measure leakage currents including DC, AC, and AC and DC stacks, generally used as a DC leakage current detection and protection in equipment that uses DC operation.
MD series sensor are type B RCD/RCM, which are used where DC residual currents could occur, in addition to normal AC, can detect high-frequency AC and pure DC earth leakage currents. The tripping conditions are defined with different frequencies from 50Hz to 1kHz. Reducing the risk of fire or electrocution through output digital alarm signal. MD series Type B RCD is an ideal protection device against different leakage currents in applications of electric vehicle charging, photovoltaic systems (solar panels), industrial device, medical device, new energy, DC screen, fire distribution cabinet, IOT field etc.
