Step-Down Center-Tapped Power Transformer – Primary 220V AC
This 18V-0-18V AC 2A Center-Tapped Step-Down Power Transformer is highly suited for constructing dual-rail DC power supplies, linear audio amplifiers, motor control circuits, and industrial instrumentation. Featuring a center-tapped secondary winding 18\text{V} - 0 - 18\text VAC it can deliver either dual 18V AC outputs or a single combined 36VAC output across the outer terminals at a 2 Amp (72VA) capacity [1.2.2]. Manufactured with high-permeability silicon steel EI laminations and high-temperature copper windings, this transformer provides excellent dielectric isolation, minimal core loss, and reliable thermal stability for continuous duty applications [1.1.1, 1.2.2].
