6. OUTPUT
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
the output, the unit might charge the capacitor in the Hiccup
PLUS
mode.
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.
Factory settings Typ. 24.1V ±0.2%, at full load and cold unit
Line regulation Max. 10mV Between 85 and 300Vac
Load regulation Max. 50mV Between 0A and 6A, static value, see Fig. 6-1
Ripple and noise voltage Max. 50mVpp Load >0.2A, Bandwidth 20Hz to 20MHz, 50Ohm
Max. 200mVpp Load <0.2A, Bandwidth 20Hz to 20MHz, 50Ohm
Output current Nom. 6A
1)
At 24V and an ambient temperatures below 45°C
Nom. 5A At 24V and 60°C ambient temperature
Nom. 3.8A At 24V and 70°C ambient temperature
Nom. 5.1A
1)
At 28V and an ambient temperatures below 45°C
Nom. 4.3A At 28V and 60°C ambient temperature
Nom. 3.2A At 28V and 70°C ambient temperature
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.
Overload behaviour Continuous current Output voltage > 13Vdc, see Fig. 6-1

Output voltage < 13Vdc, see Fig. 6-1
Overload/ short-circuit current Max. 7.5A Continuous current, see Fig. 6-1
Typ. 9A Intermitted current peak value for typ. 1s
Load impedance 50mOhm, see Fig. 6-3
Discharge current of output capacitors is not
included.
Max. 3.5A Intermitted current average value (R.M.S.)
Load impedance 50mOhm, see Fig. 6-3
Output capacitance Typ. 2 000μF 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.
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.
2) Hiccup
PLUS
Mode:
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.
