Test Jacks
Test jacks for measuring the output voltage Vo or Vo1 are
located at the front of the converter. The positive test jack is
protected by a series resistor (see: Functional Description,
block diagrams). The voltage measured at the test jacks is
slightly lower than the value at the output terminals.

Wiring for output voltage 24 V, 30 V, or 48 V (double-output
models) with both outputs connected in series. A ceramic
capacitor (Co) across the load reduces ripple and spikes.
