[Shop-talk] A different battery charger question

["Karl Vacek" <KVacek@Ameritech.net>]

Working on my old Schumacher battery charger got me to thinking about
another battery charger I have.  It came from a Clarke floor machine, and
it's a heavy amperage 24-volt charger.  No fan, just a transformer and a
rectifier circuit.  But it's 24 volts, and there are NOT alternate taps on
the transformer.

 

To drop it to 12 volts, could I use a 2:1 step-down transformer in the power
line in, and thus run the transformer on 55 volts input?  Or is there any
other simple way to convert this heavy charger to 12 volts?

 

Thanks!
Karl
