Custom DIN Rail Power Supplies, Built Around Your Application
SANMU POWER provides custom DIN rail power supply OEM and ODM solutions, including electrical specifications, enclosure and labeling customization, engineering support, prototyping and production for industrial applications.
Two Flexible Cooperation Models
Whether you bring a finished design or just an idea, we have the right model to turn it into a reliable, certified DIN rail power supply.
Original Equipment Manufacturing
You provide the design, specifications and brand — we manufacture and deliver.
- ✓Build to your drawings & BOM
- ✓Private-label enclosure & packaging
- ✓Strict specification & tolerance control
- ✓Stable supply & volume production
- ✓Confidentiality & IP protection (NDA)
Original Design Manufacturing
You share the requirement — our engineers design, prototype and manufacture it for you.
- ✓Full engineering & circuit design
- ✓Concept → Prototype → Certification
- ✓Mechanical & thermal optimization
- ✓Custom firmware / control logic (if needed)
- ✓Turnkey product ownership
What You Can Customize
Concrete, evidence-oriented options — from electrical performance to final packaging. Tell us what you need; we will engineer it.

Evidence-Oriented, Engineer-Led Customization
We focus on facts you can verify — specifications, test reports and documented processes — rather than vague marketing claims.
Specification-Driven
Every customization is documented in writing — electrical, mechanical and labeling.
Engineering Support
Dedicated engineers through design, prototype, testing and production stages.
Prototype Before Volume
Validate form, fit and function before committing to mass production.
Quality & Traceability
100% QC with batch records, test reports and full traceability.
