Custom Transformer Manufacturing Services

At Pacific Transformer, we are an industry leader in custom transformer manufacturing. Our services include no-cost transformer design, engineering, and prototyping, and we provide all the documentation necessary for UL, CSA, ETL, and TUV certifications. With more than 40 years of experience and factories in the United States, Mexico, Thailand, and China, we provide an affordable and risk-free international manufacturing solution. Our custom transformers are used in performance-critical applications across various industries, including medical, the U.S. Military, space exploration, and others. Our service model involves complete engineering and design support. We build prototypes in our Anaheim, California facility and deliver them thoroughly tested within a two-week timeframe. Once the prototype is approved, we manufacture transformers in one of our ISO 9001/AS9100 certified plants. We manage all of the logistics and quality assurance. Our workmanship is compliant with IPC 610 standards, and our total quality management approach involves electrical testing and inspection of every unit that comes off the factory floor. With our magnetic engineering and power transformer design qualifications, we design, develop, and manufacture a wide range of custom and complex transformer types. Along with toroidal, switching, and low-profile designs, we supply everything from small CES units to large transformers up to 750 KVA. We use a lean, cell-based manufacturing framework to ensure quality and consistency. We accept orders for one to tens of thousands of units. All off-shore units are re-tested upon receipt in our Anaheim offices, where they are warehoused for just-in-time delivery. In case of supply chain interruption, we manufacture the transformers in our Anaheim factory to ensure a continuous supply. Customers find our quality, flexibility, and on-time performance exceptional. For more information about our custom transformer manufacturing programs or to request a quote, contact us directly.
