PRELIMINARY
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 > 0.3F 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 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
Derate linearely between +45°C and +70°
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 trip fuses on faulty output
branches. The output voltage stays above 20V.
Overload behaviour Continuous current For output voltage above 13Vdc, see Fig. 6-1
Intermittent current
2)
For output voltage below 13Vdc, see Fig. 6-1
Overload/ short-circuit current Max. 7.2A 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) 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.
