Medical Power Adapter for Infrared Therapy Devices
1. Application Background
Infrared therapy devices emit mid or far-infrared radiation to the human body to promote blood circulation, relieve pain, and accelerate recovery. These devices require a stable and continuous power supply to ensure consistent heating of the infrared elements without electrical interference.
2. Key Roles of the Power Adapter
Stable Power Delivery: Ensures continuous and uniform heating of infrared tubes or heating plates.
Precise Temperature Control: Works in coordination with the main control circuit to maintain accurate and stable temperature outputs.
Electrical Isolation: Prevents noise or interference from the power supply reaching the user, minimizing the risk of electric shock or equipment failure.
Low Leakage Protection: Complies with IEC 60601-1 standards, making it especially safe for devices in direct contact with human skin.
Easy Installation: Suitable for desktop, wall-mounted, or portable infrared therapy units.

4. Recommended Configuration Tips
- Use a double-insulated enclosure to prevent electric shock.
- Ensure the adapter is equipped with EMI filtering to avoid interfering with other devices.
- Select adapters with built-in thermal protection to avoid overheating, shutdown, or fire hazards.
