Transformers, Double Wound (Toroidal)

A range of high quality toroidal transformers with twin 115 V AC primary windings and wide choice of secondary voltages is available from Voltamp Controls (India). The primary windings can be connected in series or parallel to cater for 115 V or 230 V, 50/60 Hz AC inputs. All leads for both primary and secondary are double-insulated enamelled wire with stripped wire ends thereby reducing assembly time. There are no air gaps in the core and no vibrating laminations. The reluctance is low, resulting in very low magnetising currents with savings in power consumption. A further benefit of this gapless core is the reduced level of radiated electrical noise (hum field). The simple construction of the toroid and the resultant saving in weight as compared to the conventional laminated transformers makes this range particularly attractive for compact power supplies and slimline equipment. Weight of conventional laminated transformer of 1 kVA is approximately 12 kg, whereas weight of Toropower toroidal transformer i
