www.pulsar.pl MSC1512 3. Operating status indication. The PSU is equipped with 2 LEDs that indicate operating status of: AC and AUX. AC- red diode: Under normal status (AC power) the diode is permanently illuminated. The absence of AC power is indicated by the AC diode going out. AUX- green diode: indicates DC power at the module’s output. Under normal status the diode is permanently illuminated. In case of a short circuit or an overload at the output, the diode is off. 4.
