CT-Series
3-PHASE, 12V, 8A, 96W
6. OUTPUT
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 unlimited capacitive and inductive loads.
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 Min. 12-15V Guaranteed value
Max. 16V 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 setting output voltage Typ. 12.0V ±0.2% at full load, cold unit
Line regulation Max. 10mV Between 323 and 576Vac input voltage change
Load regulation Max. 100mV Between 0 and 8A in “single use” mode, static value
Ripple and noise voltage Max. 100mVpp Bandwidth 20Hz to 20MHz, 50Ohm
Output current Nom. 8.0A At 12V and 60°C ambient temperature
Nom. 6.0A At 12V and 70°C ambient temperature
Nom. 6.4A At 15V and 60°C ambient temperature
Nom. 4.8A At 15V and 70°C ambient temperature
Reduce output current linearly between +60°C and +70°C
Overload behavior Continuous current See Fig. 6-1
Overload/ short-circuit current Max. 15A Continuous current, see Fig. 6-1
Output capacitance Typ. 5 200μF 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.
