The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage.

The output is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large

capacitors, such as EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance > 0.4F are connected to

Output voltage

Nom.

24V

Adjustment range

Min.

24-28V

Guaranteed value

Max.

30.0V

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.

Fuse breaking current

Typ.

15A

Up to 12ms once every five seconds, see Fig. 6-2.

The fuse braking current is an enhanced transient current which helps to

start heavy loads or to trip fuses on faulty output branches. The output

voltage stays above 20V. See chapter 23.1 for additional measurements.

Overload protection

Included

Electronically protected against no-load, overload and

short circuit. In case of a protection event, audible

noise may occur.

Output capacitance

Typ.

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.

At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 1s. After this, the

output is switched off for approx. 9s before a new start attempt is automatically performed. This cycle is repeated as long as the overload

exists. If the overload has been cleared, the device will operate normally. See Fig. 6-3.
