Important Installation Note
Each transformer is supplied with a dished washer and protection pads for single hole fixing. Ensure that the pads are fitted above and below the transformer winding and that the dished washer is on top of the upper pad. Do not overtighten the fixing bolt (not supplied) as this could damage the winding.
Under no circumstances should both ends of the fixing bolt contact a metal chassis or frame as this would create a 'shorted turn' causing irreparable damage.

Below is a small standard range of Open style toroidal transformers covering the most commonly requested power ratings and output voltages.
Nuvotem Talema also offer a custom design service, where our experienced engineers can design and offer a toroidal transformer to your exact specifications ; Multiple same or differing output voltages, centre tapped or multi-tapped secondaries, different lead lengths or materials, different mounting styles, addition of single or multipole crimped connectors, terminal blocks, etc. This list is endless.
