Mechanical Power Relays
The electronic power relay EPR10 is a solid state relay for high continuous currents. It is suitable for use in utility vehicles and special vehicles where reliability and functional safety are at a premium. At DC 24 V, the EPR10 allows a continuous load of up to 200 A.
The EPR10 is available in two different versions: EPR10-N is a relay and has no protective function. Two performance classes are available (up to 100 A and up to 200 A). EPR10-P is a protective relay and monitors both the load current and the thermal load. In the event of a critical condition, the device will automatically interrupt the circuit and will issue a group fault signal.
Note: We are preparing a separate version for applications where the current can flow in both directions. The present EPR10 design only allows one current direction.
