The module enables the soft start and limitation of the large initial current peaks of capacitive consumers. This includes all DC devices with a smoothing capacitor on the voltage input, regardless of whether the devices are sounders or ﬂashing lights. The SSM soft start module prevents the overloading of the relay contacts when switching on and the premature triggering of overcurrent circuit breakers (e.g. PLC controller). The module is available as a built-in housing for DIN rail mounting or is already integrated in various devices.
