Activating Capacitive Loads
High capacitive loads can be applied using the electronic circuit breaker. The
resulting high inrush currents strain the feeding power supply. The power supply
must be able to deliver the maximum required power without the voltage falling
below 20.4 VDC.
The capacity value to be reached depends on elementary factors, such as the
already mentioned feeding power supply, cable length and conductor cross-
section, as well as the properties of the load to be supplied.

ON delay
The channel is activated time delayed as soon as a minimum input voltage is
present. This requires that the channel was ON before switching off the input
voltage.
Behavior upon restoration of the input voltage
The circuit breaker channel adopts the state before the input voltage was
switched off. A channel that was manually switched OFF or triggered is not
automatically switched ON.
The channel is randomely activated time delayed within 170 ms … 500 ms. If
several electronic circuit breakers are connected to a power supply, larger
current spikes are avoided when switching ON.
