JOSEF DY-21C overvoltage relay voltage setting range 50-200V board front with seat

Description :

　　1、 Purpose:

　　DY-20C and 20D series voltage relays (hereinafter referred to as relays) are used as starting elements in relay protection circuits for voltage rise (overvoltage protection) or voltage drop (low-voltage lockout) of generators, transformers, and transmission lines.

　　2、 Main technical parameters

　　Action time: When the overvoltage relay is at 1.2 times the setting value, the action time is not more than 0.12s; when the low-voltage relay is at 0.5 times the setting value, the action time is not more than 0.15s; Contact capacity: In a DC inductive load circuit with a voltage not exceeding 250V, current not exceeding 5A, and time constant of 50.75ms, the breaking capacity of the output contact of the product is 50W. The output contact can reliably operate and return 5x10 "times under the specified load conditions. The long-term allowable current for the output contact is 5A.
