2.3Controls 2.3.1 Front Panel

The power supply front panel provides the following controls and indicators:

ON/OFF: Press this key to switch power to the unit ON. Press again to switch power to the unit OFF.

DC OUT 1 - 3: The blue OK LED will be lit for as long as the assigned DC output DC OUT 1, 2, or 3 pro- vides the correct supply voltage for active components.

Should the supply voltage at a DC output be shorted or fail (drop below 2 V), the output be over- loaded, or the temperature of the unit exceed the acceptable level, the OK LED for that input will extin- guish and the red FAIL LED be lit instead.
