Hello all
to best understand this i think some background is needed
i work at a heritage railway. we have some locos "class 08 shunters " that run on a 90volt system. we also have 110volts loco's and 48volts locos. an passed away member built a triac based circuit using a 230v to 110v ac transformer.
i have never worked with triac's before and looking on advice how to go about this.i could just copy the current and only charger but it not very user friendly you got use a POT to set voltage needed and well lets just say some users more than once tried charging 48v loco with POT cranked upto 110v !
i was thinking more in line of a three way selector for the three voltages but i not sure if that would work with triac circuit.
also there is next to no failsafes just MCB on pri and sec sides
