Description

The ECP-E2… electronic circuit breaker can be used in

applications that cover all aspects of the switched-mode

power supply unit.

In the event of an overload, switched-mode power supply

units reduce their output voltage, which means that all the

connected loads are no longer sufficiently supplied, e.g., in

the event of a short circuit at the load.

The solution here is the ECP-E2… electronic circuit breaker,

which selectively protects all 24 V DC load circuits. The

ECP-E2… constantly limits the residual current to 1.8 times

(or 1.5/1.3 times) the protected nominal current. Capacitive

loads can thus be switched on and loads are only switched

off in the event of an overload or short circuit.

In addition, the ECP-E2… can be controlled remotely by

means of the control input (12), for example, via a PLC, i.e.,

the ECP-E2… is electronically connected by means of an

external +24 V DC permanent signal (at connection 12),

enabling current to flow in the load circuit. Defined

shutdown, independent of the load, is carried out by

applying the ground signal at the same control input (12).

The floating auxiliary contacts of the ECP-E2… can be used

to implement a group query from connection 13 to 14. If a

circuit breaker trips or is disabled, the signal to connection

14 is interrupted.

A multi-color LED and the signal contact indicate the

operating or error state.
