How to Choose a Company
- Demand clear validation data on key performance indicators like output ripple and noise, transient response, and hold-up time for your specific load profile, not just datasheet typicals measured under ideal conditions.
- For products targeting the medical market, verify adherence to ISO 13485 quality management systems and specific certifications like IEC 60601-1 3rd Edition; for industrial applications, look for UL 508 or relevant ATEX/HazLoc approvals if operating in hazardous environments.
- Assess their in-house Design For Manufacturability (DFM) capabilities, particularly regarding thermal modeling, power factor correction implementation, and EMI/EMC mitigation strategies to ensure your integration space and efficiency targets are met without unforeseen issues.
- A common pitfall is accepting generic Mean Time Between Failures (MTBF) calculations without understanding the underlying stress factors and component derating methodologies; insist on detailed reliability predictions based on your actual operating temperature and load conditions.
- Ensure the manufacturer provides robust technical support for system-level integration, including experienced applications engineers who can assist with EMI/EMC debugging and offer guidance on critical parameters like minimum load requirements and proper grounding techniques.

Frequently Asked Questions
What specific power supply certifications are critical for my product's target market?
Certification requirements vary significantly by region and end-use. For North America, UL (Underwriters Laboratories) standards like UL 62368-1 (IT/AV) or UL 60601-1 (Medical) are crucial. For Europe, CE Marking signifies compliance with directives, often requiring adherence to IEC standards (e.g., IEC 60950-1, IEC 60335 for household appliances). Other key certifications include CCC for China, TÜV for broader European acceptance, and environmental directives like RoHS and REACH. Always confirm the specific standards applicable to your product's category and intended markets.
How should I evaluate a power supply manufacturer's Mean Time Between Failures (MTBF) claims?
MTBF is a statistical prediction of reliability, not a guarantee of individual unit life. When evaluating, ask for the calculation methodology used (e.g., MIL-HDBK-217F, Telcordia SR-332, or manufacturer-specific empirical data). Critically, inquire about the assumed operating temperature, load percentage, and component derating practices used in the calculation. A supplier that transparently provides this detail and can model MTBF closer to your actual application conditions demonstrates a deeper understanding of reliability engineering.
What's the difference between a custom and a modified standard power supply, and when should I choose which?
A custom power supply is designed from scratch to meet unique, highly specific requirements for form factor, electrical performance, or environmental resilience. It involves higher Non-Recurring Engineering (NRE) costs and longer development cycles but yields a perfectly optimized solution. A modified standard power supply starts with an existing Commercial Off-The-Shelf (COTS) unit and makes minor alterations, such as adjusting output voltages, changing connectors, adding specific features, or updating firmware. This option is faster, less costly in NRE, and suitable when COTS units are 'almost' right but need minor tweaks for seamless integration or specific performance gains.
How do I ensure a power supply will meet my product's EMI/EMC requirements?
EMI/EMC compliance is a system-level challenge, not solely dependent on the power supply. While the power supply must be designed to meet conducted and radiated emissions standards (e.g., FCC Part 15, CISPR 32), its integration into your product plays a huge role. Work closely with your chosen manufacturer, providing them with your product's physical layout, grounding scheme, and potential noise sources. Ask about their in-house EMI/EMC pre-compliance testing capabilities and inquire about common mode chokes, output filtering strategies, and proper shielding recommendations for your specific application to mitigate potential issues early in the design phase.
