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 > 1F are connected to the

Output voltage

Nom.

24V

Adjustment range

Min.

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

In “single use” mode: ±0.2%, at full load, cold unit

In “parallel use” mode: ±0.2%, at 20A, cold unit

(results to 23.9V±0.2% at 24A and 25.1V±0.2% at no

load)

Line regulation

Max.

10mV

Between 85 and 300Vac input voltage change

Load regulation

Max.

100mV

Between 0 and 24A in “single use” mode, static value

Typ.

1000mV

Between 0 and 24A in “parallel use” mode, static

value, see Fig. 6-2

Fuse breaking current

Typ.

60A

Up to 12ms once every five seconds, see Fig. 6-4.

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 24.1 for additional measurements.

Overload protection

Included

Electronically protected against overload, no-load

and short-circuits. In case of a protection event,

audible noise may occur.
