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