Output voltage control for single-output models
Notes:
– The
R-Function
excludes
option
P
(output
voltage
adjustment by potentiometer).
If the output voltages are increased above Vo nom via R-input
control, option P setting, remote sensing, or option T, the
output currents should be reduced, so that Po nom is not
exceeded.
– With double-output models the second output follows the
value of the controlled main output.
– In case of parallel connection the output voltages should be
individually set within a tolerance of 1 – 2%.

Double-output models:
Wiring of the R-input for output voltages 24 V, 30 V, or
48 V with both outputs in series. A ceramic capacitor (Co)
across the load reduces ripple and spikes.
Test Jacks
Test jacks (pin diameter 2 mm) for measuring the main
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.
