Q: What are medical power supplies?

Medical power supplies are specialized devices that provide the precise electrical power needed for healthcare equipment and medical devices. Standard power from a socket often doesn't meet the specific requirements of these devices, so medical power supplies convert incoming power to a form that's safe and suitable for medical use. Because medical devices are critical to patient care, strict global safety standards are in place to protect patients and operators. Medical power supplies must comply with these standards and receive approval from regulatory bodies like the FDA. AE designs and manufactures medical-grade power supplies that meet the IEC 60601 standard and are FDA-approved.

Q: What is a medical-grade power supply?

A medical-grade power supply is a specialized unit designed to meet strict safety standards for medical devices and equipment use. These power supplies, whether internal or external to the device, must be reliable, precise, and consistent to support accurate treatment outcomes. To achieve this, medical-grade power supplies undergo rigorous testing by regulatory authorities and are classified based on their suitability for specific medical applications. Those that meet these high standards are recognized as medical-grade. AE produces internal and external power supplies for medical use, all compliant with the IEC 60601 standard.

Q: What are the requirements for a medical-grade power supply?

To be classified as a medical-grade power supply, several essential requirements must be met: ● Low Leakage Current : The power supply must have minimal leakage current to protect operators and patients. ● Electromagnetic Compatibility (EMC): It must be designed to prevent interference with other medical equipment. ● Reliability and Environmental Resilience: The power supply should function reliably under various environmental conditions. ● High Isolation and Stability: It must maintain stable output and provide isolation from external factors. ● Robust Physical Attributes: A durable design that can withstand drops and rough handling is crucial. ● Safety Standards and Means of Protection (MOP): Compliance with safety standards and protective measures is mandatory. These requirements are essential for the safe use of power supplies in healthcare settings. AE prioritizes user safety by rigorously testing each power supply to meet and exceed these criteria. AE’s medical-grade power supplies are used in FDA-approved medical devices and trusted by leading original equipment manufacturers worldwide.

Q: What is the standard for medical power supplies?

Medical power supplies must meet specific safety standards for medical devices. The primary standard is IEC 60601-1, the international safety standard for medical electrical equipment. In the United States, this standard is recognized by the FDA; in Europe, it is known as EN 60601-1; in Canada, it's CSA 60601-1. In addition to this general standard, more specific standards are tailored to particular medical devices. These are divided into two categories: Collateral Standards: These are additional requirements that complement the general standard. For example: ● IEC 60601-1-2 covers Electromagnetic Compatibility (EMC). ● IEC 60601-1-3 addresses radiation protection. Particular Standards: These modify or supplement the general standard based on specific devices or technologies. For instance: ● IEC 60601-2-26 applies specifically to electroencephalographs.

Q: Why is it essential for medical power supplies to meet specific IEC 60601 specifications?

Medical devices carry significant risks, as failure could endanger patients and healthcare providers. IEC 60601 is a globally recognized standard that sets strict safety requirements for medical power supplies, providing enhanced isolation to prevent electrical interference with medical equipment and protecting patients and operators. Compliance with IEC 60601 prioritizes safety and facilitates international business, enabling the import and export of medical components worldwide. At AE, all products undergo rigorous in-house testing before seeking agency approval. Our power supplies meet international standards, including IEC 60601, ensuring high-quality, reliable products that our customers can trust.

Q: Can Advanced Energy customize power supplies for specific medical applications?

Advanced Energy offers standard and configurable medical-grade power supplies to suit most applications. If these options don't meet your needs, AE can customize power supplies to match your requirements. This customization can include electrical, mechanical, firmware adjustments, and more, all while complying with regulatory standards. AE's experienced engineers will collaborate closely with your team to design power supplies for your products and applications.

Q: What are the typical voltages used in medical devices?

The voltage of a medical device is the specific voltage at which the device operates safely and effectively. There is no one-size-fits-all voltage for medical applications; the required voltage varies widely depending on the device. For example, handheld devices may need as little as 1.5V, while imaging equipment might require up to 150kV. Selecting a power supply that matches your device's specific voltage needs is essential for its safe operation. AE offers a broad range of power supply products, including AC-DC power supplies from 200W to 24,000W and DC-DC converters with voltages from 0.1Vdc to 60kVdc. AE’s medical-grade power supplies provide precise and reliable voltages, are FDA-approved, and are trusted by global OEMs across various medical applications.

Q: How do you choose the right power supplies for medical applications?

First, the power supply must meet medical-grade standards and be approved for use in medical devices. It should be reliable, efficient, and compatible with the specific electrical requirements of your device. Depending on the application, the power supply might need to be compact, have high power density, fast switching speeds, and be configurable. Critical features like low ripple and noise, low leakage, high isolation, and robust protection are essential across all applications. The power supply should also perform well in various environments, maintain electromagnetic compatibility, and comply with all relevant safety standards and regulatory approvals. Finally, choosing a manufacturer offering strong technical support is essential to address any challenges.

Advanced Energy's medical power supplies include open frame, enclosed, fanless, and configurable models as well as external medical AC adapters and DC-DC modules. An AC-DC medical power supply unit (PSU) or medical DC-DC module comes with the backing of one of the largest medical grade power supply manufacturers in the world.

Most designers nowadays elect to use standard commercially available medical grade power supplies, or seek a customized medical PSU. Using power supplies that meet medical requirements, and are already pre-approved to the EN60601-1 safety standard, helps medical device and system manufacturers speed compliance testing of products. Medical OEMs can also use medically approved power supplies to minimize the risk of encountering unexpected development problems outside their own area of expertise, which might negatively impact launch targets.
