Updated 04 Feb 2012 - Forum.

We have closed our forum - News will be placed here instead.


Added 05 Feb 2012 - Price Increase.

Due to increased material and overhead costs it is necessary to increase our product prices with immediate effect.
Orders already placed before 23:59 on 04Feb2012 will be at the agreed sale or normal price.


Updated 04 Feb 2012 - Drop-Through Transformer Hole Sizes.

It appears that on certain sizes of drop through transformers that the cutout hole is too small to allow the bobbin to fit through when fitted with two rows of pins or thick wires.
It is recommended that the hole is extended by about 1/4 inch (6.5mm) on the sides with pins or thick wires.
We will change the data sheets gradually. Datasheets that have been changed will have the cutout dimensions suffixed with 'ES' (extended size).
Note that we reserve the right to change dimensions without notice although we try not to. This may be beacuse of design change or material difficulties.
We would always recommend that you get your transformers before making the chassis.


Updated 04 Feb 2012 - Rewinds and Specials Lead Time.

We carry a small stock of finished items.
Most items are made to order. Lead time is usually within two weeks.

Current Lead Times:

  • Standard Products: less than 2 weeks.
  • Special versions of standard products: 2 weeks.
  • Other special transformers: 3 to 4 weeks.
  • Rewinds 4 to 6 weeks.

Email us for specific information.
