Power Transformers

Power Transformers are electromagnetic components used to convert voltage levels, transfer electrical energy and provide isolation in power supply and electronic systems. They are widely used in AC-DC power supplies, industrial control equipment, automation systems, consumer electronics, medical devices, lighting systems, communication equipment and embedded applications.

This category includes step-down transformers, step-up transformers, isolation transformers, PCB power transformers, chassis mount transformers, toroidal transformers, control transformers and related magnetic components. These products are commonly selected based on input voltage, output voltage, power rating, frequency, insulation rating, mounting type, package style, safety approvals and application requirements.

TomatoElec supplies original Power Transformers from recognized manufacturers such as Hammond Manufacturing, Triad Magnetics, Würth Elektronik, Pulse Electronics, Bourns, TDK, Murata, TE Connectivity and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
