Control unit for operating voltage level
High-speed auxiliary relays can give unwanted operation during earth-faults in DC battery systems. The reason for operation is that the capacitance to earth will discharge through the relay due to the ground-fault, giving rise to a voltage across the relay. To avoid that risk, a control unit - type RTXV - may be connected in series with the terminal of the relay coil.
RTXV protects against misoperation of auxiliary relays due to voltage transients and other surges, and is intended for trip relays or any critical auxiliary function requiring pick-up voltage control.
Main Features:
- No delay of normal operation
- No limit to tolerated DC battery system capacitance
- Can be connected to either the positive or negative side of the auxiliary device depending on configuration
