UTPUT
The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage.
The device 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. 12V
Adjustment range
12-15V Guaranteed value
Max. 16.0V
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.

Line regulation
Max. 10mV Between 85 and 300Vac
Load regulation
Max. 50mV Between 0A and 12A, static value
Ripple and noise voltage
Max. 50mVpp Load >0.3A, Bandwidth 20Hz to 20MHz, 50Ohm
Max. 200mVpp Load <0.3A, Bandwidth 20Hz to 20MHz, 50Ohm
Output current
Nom. 12A
1)
At 12V and an ambient temperatures below 45°C
Nom. 10A At 12V and 60°C ambient temperature
Nom. 7.5A At 12V and 70°C ambient temperature
Nom. 9.6A
1)
At 15V and an ambient temperatures below 45°C
Nom. 8.0A At 15V and 60°C ambient temperature
Nom. 6.0A At 15V and 70°C ambient temperature
Derate between +45°C and +70°
Fuse breaking current
Typ. 30A
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 10V.
Overload behaviour
Continuous current Output voltage > 8Vdc, see Fig. 6-1
Intermittent current
2)
Output voltage < 6Vdc, see Fig. 6-1
Overload/ s
hort-circuit current Max. 14.2A Continuous current, see Fig. 6-1
Typ. 15A Intermitted current peak value for typ. 1s
Load impedance 50mOhm, see Fig. 6-3
Discharge current of output capacitors is not
included.
Max. 5A
Intermitted current average value (R.M.S.)
Load impedance 50mOhm, see Fig. 6-3
Output capacitance
Typ. 2 700µF Included inside the power supply
Back
-feeding loads
Max. 25V 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 7V), 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.
