hi
i have a nicad battery charger and its rating is stated as 11.6v 1.5v 18va
im a little confused as to what thee 1.5v relates to.
and second it has a center tap transformer using 2 diodes so is full wave output so is the rating applied to each tap ie can i draw more current through each half of the secodary at 12v compared to if i tapped 24v from the full coil.

thanks
it is actually printed as 1.55v but i a makes more sense. it has burnt a resistor so i cant tell its value so im slowly back working it.

no, if you connect the secondary for 24 volts, the current will be cut in half. the power in watts stays the same when you change from series to paralell secondaaries.
