1. Application scope
The JHY series integrated circuit voltage relay (hereinafter referred to as the product) is used in relay protection devices for motors, transformers, and transmission lines as a starting element for overvoltage or low-voltage lockout. This product is an integrated circuit static relay with high precision, low power consumption, short action time, high return coefficient, intuitive and convenient setting. It overcomes the disadvantages of electromagnetic relays such as easy contact shaking, high working noise, difficult adjustment of action value return coefficient, and variable action value after input.
