3.4 Output
The output provides an SELV/PELV nominal voltage that is electrically isolated from the input voltage.
The output 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 > 3F 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.
Output voltage Nom. 24V
Adjustment range Min. 24-28V Guaranteed value
Max. 30V This is the maximum output voltage that can occur in the end position of the potentiome-
ter in clockwise direction due to tolerances. It is not a guaranteed value that can be
achieved.
Factory settings typ. 24.1V ±0.2%, at full load (cold device)
Line regulation Max. 10mV Between 90 and 300Vac
Load regulation Max. 100mV Between 0 and 20A, static value, see Fig. Output voltage over output current, typ.
Residual ripple and
ripple voltage Max. 100mV

Short circuit at the output
Output capacity typ. 6,800μF Included in the power supply
Load feedback Max. 35V The device is robust and will not indicate a malfunction if a load voltage is fed back into
the power supply. It does not matter whether the power supply is switched on or off. The
absorbed energy can be calculated by means of the built-in large-size output capacitor.

2)
In case of severe overload (when the output voltage drops below 13V) the power supply delivers a continuous output current for
2-5 seconds. The output is then switched off for approx. 7 second before a new start attempt is automatically made for 1 second. This
cycle is repeated as long as the overload exists. The device starts operating normally again once the overload has been rectified.
