Name: JRV 202 212 Definite time DC voltage relay - Sai Creations
Availability: InStock

Features

Software based design

Wide auxiliary supply

Low burden

Principle of Operation:

JRV 202 provides under voltage protection and JRV 212 provides over voltage protection for DC systems. Relay operating time is determined by set definite time through front DIP switches. The relay measures the input voltage and if it exceeds the set threshold, it extends a trip signal after the operating time. The relay output contacts are self reset type. TEST button facilitates testing of relay output contacts for trip and alarm circuits.

Application:

The relay provides DC Under voltage / Over voltage protection for DC systems.
