Relays Solid State Remote Power Controller EPR10
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. 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: Pumps Ventilations Cooling systems Benefits: 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 Low investment costs: blade fuses in sub-paths and heat sinks superfluous because the EPR protects against overcurrent and short circuit Minimized 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 Less CO 2 emission: due to low internal resistance due to minor holding power Flexible design: the device switches without a sound and can therefore be installed in the passenger cabin without being noticed.

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:

  • Pumps
  • Ventilations
  • Cooling systems

Benefits:

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

Low investment costs:

  • blade fuses in sub-paths and heat sinks superfluous because the EPR protects against overcurrent and short circuit

Minimized 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

Less CO 2 emission:

  • due to low internal resistance
  • due to minor holding power

Flexible design:

  • the device switches without a sound and can therefore be installed in the passenger cabin without being noticed.
