Power transformers are critical components in many electronics and electrical applications due to their role in the transfer of electrical energy. These passive, electromagnetic devices generally rely on inductive coupling to transfer energy between circuits. During the transfer process, they also convert power-level voltages, increasing or decreasing levels depending on the application’s restrictions and requirements.

Power transformers are available in standard and custom models with a variety of designs, sizes, and ratings to suit a wide range of project requirements.

Custom Power Transformers From Triad Magnetics

At Triad Magnetics, we offer a comprehensive selection of standard and custom power transformers. Our transformers are available with power ratings ranging from 0.010VA–10kVA and frequency ratings from 20–500 kHz. Additionally, our custom transformers feature either series and parallel configurations and UL insulation systems from 130–200°C. Customers may also select from a variety of core material options, including iron, nickel, magnesium, silicon steel, and zinc.

Our expert engineers provide personalized service, working closely with customers to produce the optimal design for their unique application. To achieve this design, we maintain an ISO 9001:2015 certified design center (located in Perris, CA), where we perform extensive custom design operations with a focus on rapid design, prototyping, and testing. Combined with the knowledge and skill of our engineers, this facility allows us to modify standard products or produce entirely custom power transformers to meet the requirements of virtually every power application.
