Electronic Overcurrent Protection

Typical Applications

Ideally suited to protect equipment components in industrial applications and supply lines which are fed by means of a DC24V switch-mode power supply.

Technology

Electronic overcurrent protection prevents dips of the output voltage of switched mode power supplies both in the event of short circuit and overload. At the same time these devices provide selective protection or disconnection. Switching high capacitive loads and indicating a functional error is possible without any problems. Fault indication is by means of LEDs and auxiliary contacts. This helps with trouble-shooting and increases machine run times.
