Core Advantages
Why engineers evaluate ProMagTech
Low DCR Flat Wire Design
Flat copper wire winding is reviewed against DCR, AC loss, thermal path and DC bias requirements. Final loss and temperature rise must be confirmed by sample test data.
Precision R&D
Engineering review starts from converter topology, current waveform, insulation requirements, thermal path and mechanical envelope. Custom design support is documented through project-specific drawings, samples and test records.
Process and test evidence
Public evidence now includes factory process photos, production equipment photos, finished-product inspection images, product files and redacted inspection records.
Overseas Engineering Support
Project communication supports overseas buyers in Southeast Asia and other export markets. Published evidence now focuses on process records, inspection scope, product files and engineering review materials.
Rapid Customization
Custom design review starts from inductance, current waveform, frequency, cooling method and mechanical envelope. Sample timing is confirmed after engineering review.
Project-specific inspection review
Inspection scope can cover inductance, DCR, DC bias, leakage inductance, turns ratio, hi-pot and insulation resistance according to the approved sample record.
