Safe, High quality and Cost-effective, Residual Current Transducer for EV Charging - TLB6-A1 Series

Safe, High quality and Cost-effective, Residual Current Transducer for EV Charging - TLB6-A1 Series.jpg

The rapid growth of the new energy vehicle industry has resulted in charging stations becoming ubiquitous in residential and commercial areas. As a public facility, it is of paramount importance to ensure the safety of these charging stations. One essential responsibility for all manufacturers is to prevent any charging leakage that may occur during the charging process.

Through extensive market research and years of technical experience, MORNSUN has the unique circuit technology and introduced the TLB6-A1 series, a safe and reliable residual current transducer for EV chargers. 


The TLB6-A1 Series presents itself as a versatile and reliable solution for the EV charger. By adopting fluxgate detection technology, it can detect residual current types such as DC, AC, and various pulsating residual currents, and meet the IEC62752 (mode 2) and IEC62955 (mode 3) residual current detection standards. It can detect the 6mA DC residual current, with a sensitive trigger for timely response to leakage events.


1. Safety and reliability with residual current detection

The product detects Type A + 6mA leakage current, which has a safer solution than the Type A products on the market.

2. Comply to IEC62752、IEC62955

TLB6-A1 series is designed to comply with IEC62955 and IEC62752, and its product action time is much higher than that specified in the IEC62752 standard, which can achieve a faster response than the standard products and a safer system residual current detection.

The following is the measured data of TLB6-A1PV. Its action time is far superior to the standard regulation.
