Default Re: Instruction on Melcher switching regulator modules type SMR126ER-7 & PSR128 Pleas

I've just had a play with the switching modules.

They all work.

The PSR128 needs a 270k resistor between R and Vo+ to give 13.8v out.

The SMR 126, requires a 2k resistor between the two "Sense" terminals to give 13.8v out.

Many thanks for the help and info.
