Medical imaging equipment: X-ray machines, CT scanners, and 4k surgical imagedisplayers those require high stability and low noise power to ensure image quality.

Medical lnstruments: Medical instruments such as electrocardiogram machines,blood pressure monitors, and respiratory devices require stable power to ensuretheir proper operation,and also need to comply with medical safety standards toensure patient safety.

Dental Applications:Dental clinics and dentalequipment requires high-quality, stable,and reliable power supply. Power supply must provide the required voltage andcurrent while maintainingthe stability of voltage and current to ensure properoperation of equipment. Dentalequipment includes teeth cleaning devices, toothrestoration equipment, dental curing lights, root canaltreatment devices, and more.

Home Care Applications: With the aging population,the demand for home care isincreasing. Power supply units can be used in various home care devices such aselectric wheelchairs, oxygen concentrators, blood pressure monitors, blood glucosemeters, insulin pumps, and others. These devices require stable and reliable powersupply to ensure long-term operation and usage.

High reliability and stability: use medical-grade filters and related components.

Ground insulation protection: cut off power to protect medical equipment and user safety.

Overvoltage protection: Avoiding overvoltage damage to medical equipment and potential safety risks.

Short circuit protection: detect short circuits in time, cut off power quickly, and avoid danger

Overload protection: Preventing damage to medical equipment and potential safety risks due to exceeding the load capacity.

Electromagnetic Compatibility (EMC): Good EMC characteristics to prevent interference with other electronic devices.

The relevant electrical safety testing standard is IEC 60601-1, which encompasses general requirements, including hazard lists and limits of acceptable risk. The parallel series of standards, IEC 60601-1-X, specify the primary objectives for electrical medical equipment systems, electromagnetic compatibility, X-ray protection, etc., and must be concurrently applicable with IEC 60601-1. The IEC 60601-2-XX series of standards apply to specific medical devices and must also be applied with IEC 60601-1 or IEC 60601-1-X standards.

Electromagnetic radiation and electromagnetic radiation protection of medical electronic devices are crucial factors that influence the design of power supply systems. For instance, compliant medical power supplies must adhere to EN 60601-1-2, which requires compliance with several technical requirements related to electromagnetic compatibility (EMC). Specifically, medical power supplies must meet IEC 61000-4-2 (electrostatic discharge immunity, requiring a level of 3kV), IEC 61000-4-3 (radiated radiofrequency immunity, requiring a level of 3V/m), IEC 61000-4-4 (electrical fast transient/burst immunity, requiring a level of 1kV), IEC 61000-4-5 (surge immunity for mains power supply, requiring levels of 1kV and 2kV), IEC 61000-3-2 (limits for harmonic current emissions in AC power systems), IEC 61000-3-3 (limits for voltage fluctuations and flicker), as well as EN 55011 (radiated emissions limits for Class A or Class B products).
