Mains > Power transformers

  Our “universal” transformers have multiple filament windings and a high voltage winding you can select from a wide range of voltages. Click the “order no” for more details
Our “custom power transformers” allow you to design your own power transformer with with up to 16 terminals. Clicking the type no will lead you to the “Custom power transformer form”
All power transformers are supplied in our black metal enclosures

Mains > Power supply chokes

Our standard chokes are dual C-core open frame types with lead out wires.
We can as well supply chokes potted in our black metal enclosures, then add “C” to Order no, e.g. C65/10H100C.
Extra cost for potted version is EU €48.00/export €40.00 Case size of the potted version for all above chokes is 87 x 71 x height 101,5m (CASE-0)
