UTPUT
The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage.
The device is designed to supply any kind of loads, including unlimited capacitive and inductive loads.
The output is electronically protected against overload, no-load and short-circuits. In case of a protection event,
audible noise may occur.
Output voltage
Nom. 24V
Adjustment range
24-28V Guaranteed value
Max. 30V
This is the maximum output voltage which can occur
at the clockwise end position of the potentiometer
due to tolerances. It is not a guaranteed value which
can be achieved.
Factory setting output voltage
Typ. 24.1V ±0.2% at full load, cold unit
Line regulation
Max. 10mV Between 323 and 576Vac input voltage change
Load regulation
Max. 100mV Between 0 and 5A in “single use” mode, static value
Ripple and n

Nom. 4.3A At 28V and 60°C ambient temperature
Nom. 3.2A At 28V and 70°C ambient temperature
Reduce output current linearly between +45°C and +70°C
Overload behavior
Continuous current See Fig. 6-1
Overload/ short
-circuit current Max. 13A Continuous current, see Fig. 6-1
Output capacitance
Typ. 3 800µF Included inside the power supply
Back
-feeding loads
Max. 35V The unit is resistant and does not show
malfunctioning when a load feeds back voltage to
the power supply. It does not matter whether the
power supply is on or off. The absorbing energy can
be calculated according to the built-in large sized
output capacitor.
1) This current is also available for temperatures up to +70°C with a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
