A voltage adjustment potentiometer can be found behind the flap on the front of the unit (see chapter 15). However,

it is not recommended to change the output voltage since load sharing between power supplies connected in parallel

can only be achieved by a precise setting of the output voltages. The factory settings allow precise load sharing and

only qualified personnel should change the adjustment potentiometer.

The maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances is

30V. It is not a guaranteed value which can be achieved. The typical value is 29.5V.

Current values between 24 and 28V can be interpolated.
