A Input Terminals (Screw terminals)
L1, L2, L3 Line input
...PE (Protective Earth) input
B Output Terminals (Screw terminals, two pins per pole)
+ Positive output
– Negative (return) output
C “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 also section 25.7. A missing jumper is equal to
a “Single Use” mode.
D Output Voltage Potentiometer
Multi turn potentiometer;
Open the flap to set the output voltage.
Factory set: 24.1V at full output current, “Single Use” mode.
E DC-OK LED (green)
On, when the voltage on the output terminals is >90% of the
adjusted output voltage
F Overload LED (red)
- On, when the voltage on the output terminals is <90% of the
adjusted output voltage, or in case of a short circuit in the output.
- Flashing,
when the shut-down has been activated or the unit has
switched off due to over-temperature.
- Input voltage is required
G DC-OK Relay Contact
The DC-OK relay contact is synchronized with the DC-OK LED.
See section 8 for details.
H Shut-down and Remote Control Input
Allows the power supply to be shut down. Can be activated with
a switch contact or an external voltage.
The remote control input allows adjusting the output voltage
between 14V and 28V. See sections 9 and 10 for details.
