Precision Built Transformers for Electrical, Industrial, and Power Conversion Systems

Sag Harbor Industries designs and manufactures custom transformers engineered for dependable performance across power supplies, control systems, instrumentation, ignition systems, and electromechanical assemblies. Our capabilities support low voltage and high voltage designs, single phase and three phase configurations, and a wide range of power ratings up to 5 KVA. Each transformer is built to meet specific electrical, thermal, and mechanical requirements, ensuring stable operation in demanding environments.

Comprehensive Transformer Manufacturing Capabilities

We produce multi tap, multi winding, toroidal, laminated, and specialty transformers tailored to customer specifications. Options include ignition transformers, negative ion power supplies, ferrite core toroidal transformers, PC mount configurations, and miniature to sub miniature designs for compact assemblies. Construction methods include potted, paper layer wound, wax impregnated, epoxy impregnated, and open frame formats. Universal (pie) windings are available for applications requiring controlled inductance and stable magnetic performance.

Engineering Expertise and Application Specific Design

Custom transformer development begins with defining voltage requirements, load characteristics, frequency, insulation class, and environmental conditions. Our engineering team collaborates with customers to determine winding configurations, core materials, thermal management strategies, and mounting formats. This ensures each transformer integrates cleanly into the final system and delivers consistent performance under operational load.

Quality Assurance and Compliance

Transformer production follows ISO 9001:2015 quality standards supported by rigorous inspection, self auditing, and operator certification programs. Each unit undergoes electrical testing for turns ratio, insulation resistance, continuity, and load performance. RoHS compliant materials and JIT/KanBan fulfillment options are available upon request. Proprietary designs are handled with strict confidentiality and controlled documentation.

Value Added Services and Customer Support

Sag Harbor Industries provides prototyping, custom labeling, encapsulation, packaging, and documentation to support downstream assembly processes. Customers receive direct communication, fast response times, and engineering guidance throughout the design and production cycle. As a U.S. manufacturer, we offer secure supply chain continuity with products fully Made in USA.
