Magnetic design is what we do.
It's not an adjacent service.
Our in-house team handles every phase: electrical design, materials selection, mechanical integration, compliance, and production engineering.
Electrical Design
Full magnetic circuit modeling and winding optimization for your specific load profile, efficiency target, and regulation requirements.
- Core selection & gap calculation
- Winding topology & layering
- Regulation & load-line analysis
- Harmonic & surge handling
Mechanical Integration
Mechanical design engineering to fit your enclosure, connectors, mounting, and service-access requirements, not the other way around.
- Envelope & dimension constraints
- Mounting patterns & hardware
- Lead-wire termination & length
- Encapsulation & vacuum impregnation
Regulatory Compliance
Design-for-compliance is built in from the start, not retrofitted after prototyping. UL, CSA, CE, IEC, and medical standards.
- UL 506, UL 5085, UL 60601
- CSA C22.2, IEC 61558, EN 60601
- RoHS & REACH compliance
- FCC & EMC considerations
Thermal & Performance
Thermal modeling, insulation system design, and accelerated life testing to ensure your transformer meets its service life.
- Class B, F, H insulation systems
- Temperature rise & hotspot analysis
- Forced air & convective cooling
- Surge & inrush characterization
Documentation & Traceability
Engineering-grade documentation from day one: datasheets, spec sheets, test reports, and full production traceability.
- Custom datasheets & 2D CAD
- IQ/OQ/PQ validation docs
- Build records & lot traceability
- PPAP / PAI support
Prototype to Production
From first-article proof-of-concept to 20,000-unit annual production, with the same team, the same quality standards, and the same accountability.
- Rapid prototype builds (1 to 4 weeks)
- First-article inspection & validation
- Design for manufacturability review
- Volume production ramp planning
A straightforward path from your idea to a production-ready design.
Define Requirements
We start with a working call to capture electrical specs, environmental conditions, enclosure constraints, compliance targets, and volume expectations.
Signed spec document & NDA
Engineering Review
Core topology, winding design, material selection, and thermal modeling, delivered back to you as a packed design proposal with 2D geometry and expected performance.
Design proposal + 2D CAD + quote
Prototype & Validation
First-article build for in-house electrical and thermal testing. Design refinement based on your validation feedback.
Prototype units + full test report
Production & Delivery
Scale up to ISO 9001 production with full lot traceability. Dedicated production engineer for the life of your program. On-time delivery.
Ongoing production + QA reports
The design conversation we love to have.
The more we know, the better we design. These are the considerations our engineers will walk through with you on your first call.
- Primary & secondary voltages (nominal + tolerance)
- Continuous VA rating & duty cycle
- Frequency (50 Hz / 60 Hz / 400 Hz)
- Ambient temp & cooling method
- Envelope / dimensional constraints
- Mounting & termination type
- Estimated annual volume
What our engineers consider for every design.
- 01
Electrical Performance Envelope
Regulation, efficiency, inrush, and load behavior, optimized for your actual operating profile, not just nameplate ratings.
- 02
Thermal Budget & Cooling Strategy
Insulation class, temperature rise, and cooling method selected to meet your service life under real-world conditions.
- 03
Safety & Compliance Architecture
Creepage, clearance, and insulation coordination designed in, so your product passes certification the first time.
- 04
Mechanical & Manufacturability
Your transformer needs to fit, mount, terminate, and install cleanly. We design with your production team in mind.
- 05
Supply Chain & Lifecycle
Material availability, second-source planning, and obsolescence management so the design serves your product for years.
