1.
INPUT POWER SWITCH (Circuit Breaker)
Circuit Breaker used as the main input ON/OFF control and protects the power source
from drawing excessive input current from the input AC line.

OUTPUT POWER SWITCH and INDICATORS
Switch used to control the output contactor of the ASX-Series Power Source. Indicators
show the state of the output contactor. The power source will enter shutdown for the case
of over-temperature or other internal fault. Shutdown is reset when the Output Power
Switch is set to OFF and the fault has cleared. (Switch not present on SCU.) Refer to
Paragraph 4.5 for details.
3.
OUTPUT COUPLING INDICATORS
LED's which show the Output Coupling of the power source.
4.

output system and has no Phase indicators. The 3 Phase indicator is not present on the
Models 120-ASX and 140-ASX.)
