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.

Applications

Powerful loads in DC 12 V and DC 24 V on-board electrical systems, which have to be supplied continuously with currents from 75 A to 200 A and which have to be switched frequently: l Pumps l Ventilations l Cooling systems l 80 % less space requirement than similar conventional solid state relays: - no heat sink required - low internal resistance through parallel connection of power semi-conductors - technically mature heat management - cooling through connecting cables l Low investment costs: - blade fuses in sub-paths and heat sinks superfluous because the EPR protects against overcurrent and short circuit l Minimised maintenance costs: - enhanced availability due to a much longer life span compared to mechanical relays - very high resistance against dust, humidity, vibration and shock due to the sealed electronic circuitry l Less CO2 emission: - due to low internal resistance - due to minor holding power l Flexible design: - the device switches without a sound and can therefore be installed in the passenger cabin without being noticed.
