Output
The output provides an SELV/PELV/ES1 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. If very large
capacitors, such as EDLCs (electrical double-layer capacitors or "UltraCaps") with a capacitance > 0.25F are
connected to the output, the device can charge the capacitor intermittently.
The output is electronically protected against overload, no-load and short circuit. In the event of a protection
event, audible noises may occur

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

The fuse switch-off current is an increased transient current that contributes to
the tripping of fuses on faulty output branches. The output voltage remains
above 40V.

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 deter-
mined 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.
2)
In the event of heavy overload (when the output voltage drops below 13V), the power supply provides
continuous output current for 2s. The output is then switched off for about 18 seconds before a new switch-
on attempt is automatically made. This cycle is repeated as long as the overload persists. After the overload
has been rectified, the device will operate normally. See Fig.
