Power Supply PS1000-A6-24.20
Output
8 Output
The output provides a SELV/PELV/EST1 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, the unit might charge the capacitor
in an intermittent mode.
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.

Fuse breaking current typ. 60A Up to 12ms once every five seconds, see Figure 8.2
The fuse braking current is an enhanced transient current
which helps to trip fuses on faulty output branches.
The output voltage stays above 20V.

Output capacitance typ. 8500μF 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.
