electric train

I have a hornby meccano 6v. circ. 1930. which i need to power. i have a speed controler plus reverse, and a paper??? capacitor
i need to get from 240v ac to 6v dc
my electrical knowlege is very basic
regards brian

Mains PSU

The easiest way is to buy a cheap PSU from maplins, etc. However, if you want to build your own, then you need a transformer, eg. WB06G from Maplin. the output from this must be rectified, preferably using a diode bridge rectifier, eg.AQ94C from Maplin. The output from this would be good enough for controlling a motor. Get someone to check the mains part for you if you are unsure of anything!

Electric Train

The closest voltage rated transformer Meccano produced was the T6 range which unfortunately gave out 9V AC to overcome inductive reactance of the 6V series wound field sideplate motors (E1 & E6). However this AC voltage would be ideal for running the train through a Variable voltage regulator such as the LM338T/K.

Electric train

An additional component required would be a bridge rectifier rated at 3-4 amps, assuming that it is the DC only loco you are attempting to run. The closest rated transformer Horby/Meccano produced was the T6(A/M)which gave 9V AC. The variable resistor in this case can be used to drop the extra voltage(incidently 12v trains were run off a 15/16V transformer).The capacitor you have is connected across the track for suppression purposes.
