DC/DC Converter (PS2)
The DC/DC converter has no provision for output power
adjustments. A green LED on front case of the power supply
indicates that the power supply is functioning properly. Using a
Digital Multimeter, measure each of the outputs of the DC/DC
converter to ensure that they meet the values specified on the
electrical schematics. Compare these measured values to those
displayed on the Operator Terminal under the Metering group.
