A
Input Terminals (screw terminals)
N, L
Line input
PE (Protective Earth) input
B
Output Terminals (screw terminals, two pins per pole)
+ Positive output
– Negative (return) output
C
Output voltage potentiometer
Open the flap to adjust the output voltage. Factory set: 24.1V
D
DC-OK LED (green)
On, when the output voltage is >90% of the adjusted output voltage
E
DC-OK Relay Contact (quick-connect spring-clamp terminals)
The DC-OK relay contact is synchronized with the DC-OK LED.
See
for details.
F
“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. 4% higher than at nominal load.
See
Parallel Use to Increase Output Power on page 21
. A missing jumper is equal to a “Single Use” mode.
