Single-Phase Primary-Switched Power Supply Unit for Universal Use – QUINT 48 V DC/20 A
Signal Loop (Figure 14)
The two signal outputs mentioned above can be
combined easily.
Example: Monitoring two devices
Use the active alarm output of device 1 and loop in
the electrically isolated alarm output of device 2. In the
event of an error, a group error message is generated.
Any number of devices can be looped.
Device 1
Output 48 V DC
Device 2
Output 48 V DC
This signal combination saves on wiring costs and
logic inputs.

7. Function
7.1. Output Characteristic Curve
With heavy loads, the working point demonstrates
the U/I characteristic curve shown in Figure 13.

The output current is limited to 25 A.
The secondary voltage is reduced until the short
circuit on the secondary side is removed.
The U/I characteristic curve ensures that both heavy
capacitive loads and devices with DC/DC converters
< 60 ° C
< 40 ° C
can be supplied by QUINT POWER in the input circuit
without any problems.
Connected fuses are reliably tripped. The selectivity

in your system con ? guration is ensured at all times.
7.2. Temperature Response
The device can supply a nominal output current of
20 A up to an ambient operating temperature of +60°C.
The output power must be decreased by 2.5% per
Kelvin temperature increase for ambient operating
temperatures over +60°C.
At ambient operating temperatures above +70°C or
in the event of a thermal overload, the device switches
off. The device switches on again automatically once it
has cooled down.
