1 Vi min will not be as stated if Vo is increased above Vo nom by use of the R input. If the output voltage is set to a higher value,
Vi min will be proportionally increased.
2 Measured with a resistive and max. admissible capacitive load.
3 Measured with a lead lenght of 0.1 m, leads twisted. Double output units with both outputs in parallel. 70/110 IMX 7 types need an
external capacitor at the input. (e.g. 1
F film or ceramic)
4 See 19 Pfl 1: Electromagnetic Immunity.
5 The DC-DC converter shuts down automatically at approx. 38 V.
6 Operation at lower input voltage possible: Po approx. 80% of Po nom at Vi min = 14.4 V.
7 Source impedance according to prETS 300132-2, version 4.3, at Vi nom.
