Output

The output provides an SELV/PELV nominal voltage that is electrically isolated from the input voltage.

The device is designed to supply any type of load, including capacitive and inductive loads.

The output is electronically protected against overload, no-load and short circuit. In the event of a protection event, audible noises may occur

Output voltage

24 V

 

Adjustment range

Min.

24-28V

Guaranteed value

Max.

30.0 V

This is the maximum output voltage that can occur in the end position of the potentiometer in clockwise direction due to tolerances. It is not a guaranteed value that can be achieved.

Safety
switch-off current

Typ.

23A

Up to 20ms once every five seconds, see Fig. Output voltage over output current, typ.
The fuse output current is an increased transient current that contributes to the tripping of fuses on faulty output branches. The output voltage remains above 20V.

Overload behavior

 

Continuous current

Continuous current, see Fig. Output voltage over output current, typ.

Output capacity

Typ.

6500μF

Included in the power supply

Load feedback

Max.

35V

The device is resistant to load feedback and will not indicate a malfunction if a load is feeding voltage back into the power supply. It does not matter whether the power supply is switched on or off. The absorbed energy can be determined by means of the built-in large-size output capacitor.

1) This current is also available for temperatures up to +70°C with a duty cycle of 10% and/or no more than 1 minute every 10 minutes.
