New Arrival: MD0630T01A-Z RCD Sensor

IVY has launched a new RCD sensor for leakage current detection, let's learn about it together

Any electrical leak can be dangerous for your staff and production site. By using IVY Residual Current Device (RCD) you can protect both staff and equipment. Thanks to its zero-flux technology expertise, IVY developed a range of highly flexible Residual Current Monitor of Type B/B+ for measuring DC and AC residual currents up to 100kHz, with digital signal output.

MD0630T01A-Z sensor is a new, compact, horizontal type rcd current sensor with pins designed for use in e-mobility infrastructure and AC charging station designs to monitor leakage currents in mode two/three/four electric vehicle charging.

MD0630T01A-Z Type A, B and B+ RCD, dedicated to detect to DC, AC and DC+AC leakage current measurement. The sensor can issues an alarm signal when the DC component of the residual current reaches a preset value. 

Q1:what is this?

A:It's an EV type residual current monitor, providing leakage protection for Mode2/Mode 3 charging and complying with the requirements of the relevant standards for leakage protection in the European/Asia-pacific/North America market for charging posts 

Q2:How does this work?

A:Smoothed DC residual currents can occur in certain power electronics applications. Smoothed DC residual currents can prevent conventional AC-type and type A residual current protection devices (RCDs) from functioning properly, with RCD inactivity or normal operation malfunction in the event of an electric shock. EV charging is a typical load that can generate a smooth DC residual current component and for effective personal safety protection, the IEC 62955 standard provides for the protection of possible smooth DC residual currents from EV charging. It effectively eliminates the loophole of AC 30mA residual current protection caused by smooth DC residual components and effectively disconnects the conductive part, making it far safer and more reliable than the combination of residual current monitoring module and relay on the charging post board.

Q3:Why do AC charging posts generate smooth residual currents?

A:The main reason is that the insulation of that part of the DC/DC inside the OBC is broken, which can be caused by driving the car for a long time, bumps and bumps, careless maintenance, etc., and then smooth DC residual current will be generated.

Q4:Why choose it?

A:This product combines 6mA DC monitoring, detection and 30mA Type A residual current protection in one device. It offers the following advantages: Safe and reliable Integrates multiple protection against short circuit, overload, residual current (sinusoidal AC, pulsating DC and smooth DC faults) in one device; the neutral pole can be opened and closed to cut off both the fire and zero wires in the event of a fault, making the charging process safer.
