1. Overview

HY series integrated circuit static voltage relays are used as starting components in overload short-circuit protection devices for motors, transformers, and transmission lines. This product is an integrated circuit static plow relay: electric
The device has high precision, low power consumption, short action time, high return coefficient, and intuitive and convenient setting. It overcomes the disadvantages of the original electromagnetic relay, such as easy shaking of contacts, high working noise, difficult adjustment of action value return coefficient, and variable action value after transportation. The product is divided into three series: HY-10, HY-20, HY-30, which can replace electromagnetic relays such as DJ-100, DY-20, DY-30, etc. respectively. At the same time, it also solves the unreliable disadvantages of the same type of JY-10, 20, 30, JY-1A, 1B, 1C, JY8-10, 20, 30 'energy instability, and large setting variation. Equipped with an auxiliary power supply, it has added dual-purpose functions for both AC and DC
