Product Introduction
A key advantage of this 12V bistable latching relay is its incredibly low power consumption; it only requires a brief pulse to switch states (set or reset) and maintains that position without any continuous power draw, eliminating heat generation and saving energy. This feature, combined with advanced magnetic arc extinguishing technology, ensures a long operational life and high reliability under strong impact conditions.
The TL802-50A is an ideal solution for modern applications like smart energy meters, electric vehicle (EV) charging pile control boards, special power equipment, and robust power supply modules, where dependable switching and energy efficiency are paramount. Its design complies with international standards, including IEC62055-31 UC3 and CE certification, and is RoHS compliant, making it a responsible choice for global markets.
