6.3 Activating Capacitive Loads
High capacitive loads can be applied using the electronic circuit breaker. The
power supply unit providing power to the device must be capable of supplying a
voltage of at least 18 VDC, even at the maximum required current. The required
current can be set using the rotary switch.
The tables below gives some standard reference values determined in experiments
with 24 VDC input voltage:
