FAQ

What makes a power supply suitable for medical devices?

Medical devices have more demanding safety, reliability, and regulatory requirements than general-purpose electronics. A suitable power supply must offer reinforced insulation, low leakage current, and excellent electromagnetic compatibility (EMC). It also needs to comply with standards like IEC 60601-1, which governs electrical safety for patient-connected devices.

In addition to hardware requirements, documentation is essential. Medical device approvals often require detailed test reports, traceability, and quality certifications such as ISO 13485. That means your power supply needs to be supported by a manufacturer who can provide this information and commit to long-term production.

Another factor is the ability to handle continuous use in a clinical environment. Medical power supplies must perform reliably under 24/7 operation, maintain stable output, and support clean shutdown and surge protection features to avoid damaging sensitive components.

If your product includes sensors, motors, displays, or data transmission modules, the power supply must be designed to support each load type safely. Custom power supply design ensures you meet these needs without unnecessary bulk or inefficiency.

Choosing a medical-grade power supply—and a manufacturer who understands medical compliance—is key to getting your device approved, launched, and trusted in healthcare environments.

What certifications are required for medical power supplies?

Medical power supplies are held to some of the highest safety and performance standards in the electronics industry. The most critical certification is IEC 60601-1, which ensures electrical safety for patient-connected equipment. This standard sets requirements for insulation, leakage current, creepage distances, and dielectric strength.

For the North American market, UL 60601-1 (or its equivalent under cULus) is required, verifying that the product complies with U.S. and Canadian safety codes. In the EU, CE marking is necessary and typically includes compliance with EN 60601-1, RoHS (for hazardous substances), and EMC directives.

Other important certifications include:

• FCC: For managing electromagnetic interference (EMI) in wireless and electronic systems
  
• ISO 13485: A quality management standard specifically for medical device manufacturers
  
• DOE Level VI or Energy Star: Energy efficiency standards (especially important for external adapters)
  

Regulations may vary by country, so it’s important to work with a manufacturer that understands your target markets. That includes knowing how to update certifications if a component changes or a redesign is required.

Your power supply should not only meet technical specs—it should arrive with all the paperwork and certifications needed to pass review. That’s why it’s best to work with a supplier that builds compliance into the design from day one.

Can I use an off-the-shelf power supply for a medical device?

While off-the-shelf power supplies may be suitable for initial prototyping or internal testing, they often fall short for production-level medical devices. Why? Because they typically aren’t certified to medical standards like IEC 60601-1, and may not offer the insulation, leakage current limits, or EMI shielding required in clinical settings.

Another consideration is longevity. Medical devices often have lifespans of five to ten years or more. If you use a commercial-grade power supply that becomes obsolete or unavailable after a year or two, you could face costly redesigns or even the need to re-certify your device.

Off-the-shelf power supplies also tend to be less optimized for the specific demands of medical electronics. For example, they might generate more heat, lack smart safety features, or fail under continuous-use conditions.

If your device needs to meet FDA, CE, or other regional approvals, you’ll need a power supply with supporting documentation, compliance test results, and long-term lifecycle management. That’s something only a medical-grade manufacturer can offer.

In short: while off-the-shelf supplies may be faster and cheaper in the short term, a certified, purpose-built power supply is the smarter—and safer—long-term solution for medical OEMs.

What are the most common customizations in medical power supplies?

Medical power supplies are frequently customized to meet the unique electrical, mechanical, and compliance needs of a specific device. Some of the most common customizations include:

• Output voltage and current configuration: To support specialized sensors, motors, or displays
  
• Form factor and mounting style: For integration into compact or sealed enclosures
  
• EMI shielding and noise suppression: To reduce interference with sensitive components
  
• Low leakage current design: Especially important for patient-connected equipment
  
• Thermal management features: Passive or active cooling options to maintain temperature control
  

Medical OEMs often request custom cable assemblies, connectors, and enclosures that support easy sterilization or reduce cross-contamination risk. Others may need redundant power features, alarms, or remote monitoring capabilities for diagnostic tools or surgical systems.

Custom power supplies can also be pre-certified to IEC 60601-1, saving you time during the regulatory process. Manufacturers experienced in medical compliance can help guide you through the process, ensuring your supply meets all applicable standards from the start.

With the right design support, a custom power supply can simplify your system architecture, improve performance, and reduce certification risk—all while fitting perfectly into your product.
