DEFINITE TIME DC VOLTAGE RELAY JRV 202

OVERVIEW

    Features

  • Software based design
  • Wide auxiliary supply
  • Low burden

Application:

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

DEFINITE TIME DC VOLTAGE RELAY JRV 202

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.
