1 Ui min will not be as stated if Uo is increased above Uo nom by use of the R or the Trin input. If the output voltage is set to a higher value,
Ui min will be proportionately increased.
2 Measured with resistive and max. admissible capacitive load.
3 Source impedance according to prETS 300132-2, version 4.3.
4 Measured with a lead length of 0.1 m, leads twisted. Double output units with both outputs in parallel.
5 Input undervoltage lock-out at typ. 80% of Ui min.
6 Short time operation down to Ui min >14.4 V possible. Po reduced to approx. 85% of Po nom.
7 Short time operation down to Ui min >43.2 V possible. Po reduced to approx. 85% of Po nom.
8 20 IMX 15 types require 4.7
F/50 V capacitance accross the input (Polyester, Philips 372 series).
9 See: Transient ETR 283 (19Pfl1), Electromagnetic Immunity.
10 Initial start-up at 9 V, main output voltage regulation down to 8.4 V.
