Remarks:
– The R-Function excludes option P (output voltage adjust-
ment by potentiometer).
– If the output voltages are increased above
Uo nom via R-
input control, option P setting, remote sensing or option
T, the output current(s) should be reduced accordingly so
that
Po nom is not exceeded.
– The R-input (as well as option P) is related to the main
output.
– With double output units the second output follows the
value of the controlled main output. Resistor values as
indicated for the single output units should be used.
– For correct output voltage adjustment of double output
units the external wiring of the outputs should be accord-
ing to:
R-function for different output configurations de-
pending upon the desired output conguration.
– In case of parallel connection the output voltages should
be individually set within a tolerance of 1...2%.

Output voltage control for single output units LK 4000 by
means of the R input
Programmable Output Voltage (R-Function)
As a standard feature, the modules offer an adjustable out-
put voltage, identied by letter R in the type designation.
The control input R (pin 16) accepts either a control voltage
Uext or a resistor Rext to adjust the desired output voltage.
When not connected, the control input automatically sets
the output voltage to
Uo nom.
a) Adjustment by means of an external control voltage
Uext
between pin 16 (R) and pin 14:
The control voltage range is 0...2.75 V DC and allows an
output voltage adjustment in the range of approximately
0...110%
Uo nom.
Uo
Uext = –––––– 2.5 V (approximate formula)
Uo nom
b) Adjustment by means of an external resistor:
Depending upon the value of the required output voltage
the resistor shall be connected
either: Between pin 16 and pin 14 (
Uo < Uo nom) to
achieve an output voltage adjustment range of approxi-
mately 0...100%
Uo nom
or: Between pin 16 and pin 12 (
Uo
> U
o nom) to achieve
an output voltage adjustment range of approximately
100...110%
Uo nom.
Warning:
–
Uext shall never exceed 2.75 V DC.
– The value of
R'ext shall never be less than the lowest
value as indicated in table
R'ext (for U0
> U
0 nom) to
avoid damage to the unit!
