What our customers say
"I think your fourth sentence is worth a gallon of good coffee— “… all the energy stored in the core during the FET on cycle is dumped out the secondary during the off time and that the secondary will fly up to whatever voltage it needs too, to dump the energy.” None of the literature I’ve read presents this idea so clearly and concisely."
"I would like to express our appreciation for your efforts in making this a successful project for us, especially to George for his expertise in refining the design and to your production for executing flawlessly. We achieved very high levels of consistency in our build, at least in part due to the very consistent performance of the magnetics."
"We solicited a new transformer design from E Craftsmen when a competitor of theirs was unwilling to improve on an underperforming product for us. The design proved perfect for the application resulting in many hundreds of flawless units being deployed in transit vehicles throughout the world. Thank you E Craftsmen for one thing we never have to worry about."
