Output
The output provides a SELV/PELV/ES1 rated voltage, which is galvanically
isolated from the input voltage.
The output is electronically protected against no-load, overload, and short
circuit. If there is a protection event, audible noise may occur.
The output is designed to supply any kind of loads, including inductive and
capacitive loads. Capacitive loads should not be larger than 2200 μF with 5 A or
8000 μF with 2.5 A additional current load.
At heavy overloads (when output voltage falls below 8V), the device delivers
continuous output current for 20 ms. After the 20 ms have passed, the output
is switched off for 170 ms before a new start attempt is automatically
performed. This cycle is repeated as long as the overload exists.
Attributes Values Notes
Output voltage Nom DC 12V —
Adjustment range
Min 12…15V Guaranteed value
Max 15.5V
This is the max output voltage that can occur at the clockwise end position of the
potentiometer due to tolerances. It is not guaranteed that this value can be achieved.
Factory settings Typ 12V ±0.2%, at full load and cold unit
Line regulation Max 10 mV Between 90…300V AC
Load regulation Max 100 mV Between 0…5 A, static value, see Figure 10
Ripple and noise voltage Max 100 mVpp Bandwidth 20 Hz to 20 MHz, 50 Ω
Output current
Nom 5.0 A At 12V and an ambient temperature below 60 °C (140 °F)
Nom 3.8 A At 12V and 70 °C (158 °F) ambient temperature
Nom 4.0 A At 15V and an ambient temperature below 60 °C (140 °F)
Nom 3.0 A At 15V and 70 °C (158 °F) ambient temperature
Overload behavior
— Continuous current Output voltage above 8V DC, see Figure 10
— Intermittent current Output voltage below 8V DC, see Figure 10
Overload/ short-circuit current
Max 7.0 A Continuous current, see Figure 10
Typ 9.0 A
Intermitted current peak value for 25 ms typ, Load impedance 150 mΩ, see Figure 11 .
Discharge current of output capacitors is not included.
Max 3.2 A Intermitted current average value (R.M.S.) Load impedance 150 mΩ, see Figure 11 .
Output capacitance Typ 2200 µF Included inside the power supply
Back-feeding loads Max 16V
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.
