Auto Transformer Compact - Efficient - Economical - Toroidal Transformer By Voltamp

A range of high quality toroidal transformers with one 230V AC. winding and taps provided as per requirement. All leads for both input and output are double-insulated enameled wire, with stripped & tinned wire ends thereby reducing assembly time. There are no air gaps in the core & no vibrating laminations. The simple construction of the toroid results in savings in weight as compared to the conventional laminated type transformers. High conductivity copper windings on insulated toroidal core made of high grade cold rolled grain oriented silicon steel ensures very low magnetizing currents & results in savings in power consumption making this range particularly attractive for compact power source and slimline equipment. A further benefit of this gapless core is the reduced level of radiated electrical noise (hum field).

Note:

Each transformer is supplied with a dished washer, protection pads and nut, bolt and washer for single hole fixing. The pads are to be fitted above and below the transformer winding and the dished washer on top of the upper pad. 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.
