Mode 3 is an AC->AC EV Charger that works by being connected to the AC supply network. It is usually located in the home that owns an electric vehicle, or in many public commercial places such as airports, hotels, workplaces, and dealerships.
J&D Electronics, by itself, has developed and produced the devices that Mode 3 consists of for the safety and efficiency of Mode 3. Based on that, AC EV slow chargers and AC smart meters are developed, and through this, an optimized CTs have been launched to improve safety and efficiency by being integrated with these devices.
In other words, for AC smart meters, JDTN series DC Tolerance CTs have been developed, so that they are not affected by DC when AC current is input, and RCD series CTs, which have been certified with IEC 62955 safety certification standards for residual current monitoring.
Above all, J&D CTs are the RCD (Residual Current Device) and have a function to detect leakage current to comply with safety certification IEC 62955. This is an element that supports the function to cut off the power of the house at the moment when a leakage current of 30mA (AC) and 6mA (DC) or more is detected in all of the user’s home electrical panels.
