Output and threshold adjustment
The adjustment of output values and monitoring thresholds are very easy. All values are adjusted
using front keys by indicating the actual value at the front side digital displays.
At normal operation mode the top display indicates the output voltage (V
O1
) and the bottom display
indicates the output current (I
O
).
For any adjustment please follow the following instructions:
press both keys UP/DOWN (
) together for a short time; the SMPS changes to adjustment
mode
press the key UP (
) or DOWN (
) to change the adjustment parameter (see also table below)
press both keys UP/DOWN (
) together for a short time; the SMPS changes to value change
mode
press the key UP (
) or DOWN (
) to change the adjustment value (if you hold the key the value
changes quicker)
press both keys UP/DOWN (
) together for a short time; the SMPS changes back to adjust-
ment mode (at this moment the changed value will be storaged)
press both keys UP/DOWN (
) for approx. 3 sec. to change back to operation mode

The monitoring thresholds automatically follow the adjusted nominal values of the output voltage.
The monitoring thresholds for mains/step-up-converter and over heating are not changeable.
You can find the adjustment ranges for several thresholds at technical specifications.
