PEB 2025
Programmable output current and thermal shut down guards the IEPC against overloads.
The IEPC offers a special transient permitted overload state. Momentary overloads within a
specified range e.g. by connecting a TE to a powered line, however, will not activate the current-
limit-circuits of the power controller. If overload is detected, the line driver will turn off according to
a time and current dependent turn off characteristic.
The IEPC offers an automatic restart-mode. In this case the IEPC tries to power up the line
periodically, thus the feeding of a line will return automatically after the overload-conditions are
removed.
