Lever Frame and ac circuits

Postby FCA » Mon Mar 16, 2015 9:49 am

Having successfully built the Society's excellent lever frame and fitted it with the recommended SPDT micro switches I am now struggling to complete the necessary wiring loom to operate Tortoise motors. The Tortoise instructions for an ac supply show two diodes in the circuit. Electrics are not my stong suit so does anyone know what the specification for these diodes is and where I can buy some?

Any electronics parts supplier will have them,
For up to 50 tortoises a pair of 1N4001 will do, these are 1 amp rated,
for more than that 1N5401 is rated at 3 amps.

If you are in UK in reach of a Maplins its probably the most economical for small orders.
1N4001S, Maplin part QL73Q is 49p
1N5401, Maplin part QL82D is 59p.

Mail order houses such as Rapid, Farnell, RS, CPC, have them at a fraction of this price but either have minimum order values or prohibitive postage, CPC is best for small orders and the diodes are about 40p for 10 but minimum order is £10 for credit card.

It might be worth doing a search on eBay or Aliexpress if you can wait a couple of weeks for the post from China!

Sorry Keith, only just picked up your second posting. Thank you very much for the offer but Maplins already have my order which I placed immediately after reading your first post.

Thanks again, Richard
