The Heart of The EV Chargers RCD Module

The increasing popularity of electric vehicles has led to higher demand for electric vehicle chargers. However, safety concerns for EV chargers are also on the rise. To ensure the safety of people and equipment, leakage current protection devices are important safety features for electric vehicle chargers. Because they can detect leakage currents in the circuit and automatically cut off the power supply. This article introduces a new type of leakage current protection device, the Type B(Type A+ 6mA DC), for electric vehicle chargers.

Type A leakage current protector is an important device for detecting leakage current in AC and DC circuits. They can detect continuous or intermittent leakage currents as well as pulsed leakage currents. Additionally, they can detect capacitive leakage currents in circuits. Type B leakage current protector can detect leakage current in AC and DC circuits, including pulse leakage current, capacitor leakage current and ground fault current. However, Type B leakage current protection devices (RCCB) are expensive and can add hundreds of dollars to the cost of a home charging station, making them difficult for consumers to purchase.

In order to solve this problem, IVY developed Type B (Type A+ 6mA DC) leakage current sensor. Its function is the same as the B-type leakage protector, it is highly safe and can be directly used in household circuits. If you purchase a relay (IM-NE801A) to use with it, its functions are equivalent to Type B RCCB, and the cost is cheaper than Type B RCCB, and our products are small in size. MD series leakage current sensors have the following outstanding features.

AC and DC integrated monitoring

One of the outstanding features of the MD series is the ability to monitor AC and DC current. The sensor is capable of detecting AC currents of 3~100mA and DC currents of 2~15mA, ensuring comprehensive protection of the system. This versatility makes it ideal for handling a variety of current types, including charging stations associated with electric vehicles.

Type B residual current protection

The MD series is a type B residual current sensor. The name is important because it means that it can detect not only sinusoidal AC currents, but also non-sinusoidal AC and pulsating DC currents. In the era of rapid development of electric vehicle charging, MD series B-type sensors ensure the highest level of safety by detecting the most complex current waveforms.

In line with international standards

The MD Series reflects its commitment to safety and quality, complying with not one but three international standards: IEC62752, IEC62955 and UL2231. This extensive certification assures users that the sensor adheres to strict global safety guidelines, making it a reliable choice for a variety of applications.

In summary, IVY’s MD series represents an important step forward in the field of residual current sensing. With its Type B protection, ability to monitor AC and DC currents and compliance with international standards, it sets a new benchmark in charging station safety. If you are looking for reliable and versatile residual current monitoring, the MD Series is the solution you have been waiting for.
