Single Secondary Step-Down Power Transformer lucky sky
This compact 0-15V AC 1A Single Secondary Step-Down Power Transformer is designed for low-power electronic circuits, linear AC-DC power adapters, relay boards, and industrial control instrumentation. Constructed with a standard single secondary winding, it efficiently steps down primary AC mains voltage (220V AC) to a stable 15V AC output at up to 1 Amp (15VA capacity). Built with high-permeability silicon steel EI laminations and durable copper wire windings, it delivers excellent voltage regulation, minimal heat generation, and reliable dielectric isolation between primary and secondary circuits.
