Switch type

“low side switch”

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

Benefits

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

- 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.
