R Control for Output Voltage Adjustment
Note: With open R input, Uo
≈ U
o nom. R excludes option P.
The output voltage Uo can either be adjusted with an ex-
ternal voltage (Uext) or with an external resistor (R1 or R2).
The adjustment range is 0…108% of Uo nom. The mini-
mum differential voltage
DUio min between input and output
(see: Electrical Input Data) should be maintained. Under-
voltage lock-out = Minimum input voltage.

LED Output Voltage Indicator
A yellow output indicator LED shines when the output volt-
age is higher than approx. 3 V.
