The setting value of JOSEF voltage relay JWY-31B 15-130V is linearly adjustable

Description :

　　purpose

　　1. The JWY series non auxiliary source voltage relay is used in relay protection devices for generators, transformers, and transmission lines as a starting element for overvoltage protection or low-voltage lockout. This relay is an integrated circuit static type relay with high precision, low power consumption, action time period, high return coefficient, intuitive and convenient setting, wide range, and no shaking phenomenon when used as a low-voltage relay. It can replace electromagnetic voltage relays without the need for DC auxiliary power supply.

　　2. The JWY series non auxiliary voltage electrical appliances are divided into three series: JWY-10JWY-20JWY-30, which can replace the DJ-100, DY-20C, DY-30 and other series of electromagnetic voltage relays. The JWY series integrated circuit voltage relay uses a dip switch to set the voltage value and a digital multiplier switch to switch. No verification is required after changing.
