    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%.

    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!
