The FETK-S1.1 implements reverse voltage protection in the same range
and may be used only with central load dump protection.
24 V vehicles require U
12 V vehicles don't require special disturbing pulse reductions.
NOTE
The FETK-S1.1 will accept permanent power supply voltage dips (for addi-
tional details of 3 V low voltage operation, see ISO standard 16750).
