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
25.6. 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: 48.0V 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
Input
Allows the power supply to be shut down. Can be activated
with a switch contact or an external voltage.
