All potentiometers and all the inputs and the outputs of the analogue interface provide a forced isolation. It is to
ensure a protective isolation for the 300Vdc.

The DC voltage and the current can be adjusted with a high precision 15 turn potentiometer with low
temperature fading. The factory setting is to the rated voltage & current from the table above. Due to the
tolerances of the potentiometers, the lower margin of the output voltage can be adjusted below the upper
threshold margin of the DC Power Good Relay (see p.6). To ensure a proper operation, the DC voltage setting
must stay above the upper hysteresis level of the Power Good Relay. We guarantee the above given
adjustment ranges with a tolerance of -5/0% for the lower margin and 0/+5% for the upper margin.
