L1, L2, L3 Phase input
PE (Protective Earth) input
C Output voltage potentiometer
Open the flap to set the output voltage. Factory set: 48.0V
D “Parallel Use” “Single Use” selector
Set jumper to “Parallel Use” when power supplies are connected in
parallel to increase the output power. In order to achieve a sharing of
the load current between the individual power supplies, the “parallel
use” regulates the output voltage in such a manner that the voltage at
no load is approx. 5% higher than at nominal load. See also Fig. 6-2.
A missing jumper is equal to a “Single Use” mode.
Factory setting is “Single Use” mode.
E DC-OK LED (green)
On when the voltage on the output terminals is > 36V
