Recent Work
We Do Power Perfectly
Years of expertise guarantee a smooth process from design to completed parts.
Production runs from five pieces to 100,000 pieces we design and manufacture power
transformers for virtually any application. In addition to optimizing electrical performance, our designs
incorporate critical end-use factors including:
- Physical dimension
- Thermal requirements
- Temperature extremes
- Performance at altitude
- Operation under shock and vibration
