Power Relay EPR10
Description
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
Technical data (25 °C)
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

75 A, 100 A, 125 A, 150 A, 175 A, 200 A
Benefits
Max. overvoltage 36 V DC
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 Less CO₂ emission:
- due to low internal resistance
- due to minor holding power

connecting the device is imperative to avoid
damage of the relay.
l Flexible design:
- the device switches without a sound and can therefore be
installed in the passenger cabin without being noticed.
