In recent years, the rapid growth of the new energy vehicles industry has increased demand for EV charging stations. Manufacturers strive to enhance their competitiveness in this evolving market. How can we ensure electrical installation protection and prevent electric shock hazards during EV charging? According to IEC 61581-1, each charging station must use a residual current device (RCD) for current sensing and system-wide protection.

As a leading power supply manufacturer and innovator, Mornsun offers safe, reliable and cost-effective TLB6-A1 series residual current transducer compliant with IEC 62752 and IEC 62955 standards that help enhance the competitiveness of your EV charging system. With compact size, multiple package designs, high reliability, fast response speed, and excellent accuracy, they provide complete protection while reducing design and maintenance costs for customers.

The selection of the appropriate Residual Current Device (RCD) for protection depends on the specific requirements of the system. Different types of RCDs can detect different types of residual currents. During the EV charging process, different types of residual currents, such as residual sinusoidal AC currents, residual pulsating DC currents and residual smooth DC currents, may generate in the EV charging system. With decades of experience, Mornsun offers accurate and fast current detection solution for EV chargers - Residual Current Transducer with in-house designed core ICs. They can detect Type A + Smooth DC of 6mA residual currents and have sensitive trigger for timely response, surpassing the Type A and Type AC RCD solutions.

Mornsun TLB6-A1 series residual current transducer offers compact size and multiple package designs, meeting various board layout and installation requirements for both single-phase and three-phase inputs. This flexibility makes it easy to install and meets different application scenarios.
