Lying on a hospital bed, watching the fluctuating curves on patient monitors, feeling the steady operation of ventilators, or undergoing ultrasound examinations — have you ever wondered what serves as the core power source for these sophisticated medical devices?
The answer lies in medical power supplies, special power units that bear life-saving responsibilities despite their ordinary appearance. Distinct from mobile phone chargers and computer power adapters, medical power supplies are manufactured under the most stringent industry standards. Founded in 1999, Zhuhai Xinhe Electric Appliance Co., Ltd. (short name: Zhuhai Xinhe Power Supply) has specialized in the medical electronics industry for 27 years. It adheres to rigorous technical specifications to guarantee safe and stable operation throughout all medical diagnosis and treatment procedures.

As the R&D Director of Zhuhai Xinhe Power Supply puts it vividly: "If ordinary power supplies are family cars, medical power supplies are Formula 1 racing cars — they require not only high efficiency but also absolute safety and stability under all working conditions."
II. IEC 60601-1: The Universal Safety Standard for Medical Power Supplies
Released by the International Electrotechnical Commission (IEC) in 1977, IEC 60601-1 Medical Electrical Equipment - Part 1: General Requirements for Basic Safety and Essential Performance is regarded as the core guideline for medical power supply design, having undergone four major revisions to date.
Core Safety Specifications
-
Electric Shock Prevention
Patient leakage current must be controlled at the microampere level. Zhuhai Xinhe Power Supply’s XH-PS series medical power modules have obtained TUV authoritative certification, with leakage current kept below 5μA, exceeding standard requirements.
-
Insulation & Isolation Performance
Adopt reinforced insulation and protective earthing for dual protection. Products applied to cardiac CF-grade medical devices support 4000V AC withstand voltage.
-
Electromagnetic Compatibility (EMC)
Medical power supplies must resist external electromagnetic interference and avoid becoming interference sources themselves. All products of Zhuhai Xinhe Power Supply pass YY0505-2012 (equivalent to IEC 60601-1-2) EMC tests, ensuring stable operation in strong electromagnetic environments such as MRI and CT examination rooms.
-
High-reliability Design
All core components undergo strict screening with industrial and military-grade materials adopted. The repair rate of Zhuhai Xinhe medical power modules is lower than 0.1%, reaching world-class standards.
III. Zhuhai Xinhe Power Supply: A Hidden Champion with 27 Years of Medical Power Expertise
Since its establishment in 1999, Zhuhai Xinhe Electric Appliance Co., Ltd. has focused on two core businesses: medical power supplies and trackball modules, providing reliable power support for B-ultrasound scanners, patient monitors, infusion pumps, hemodialysis machines and other mainstream medical equipment.

Practical FAQ for Medical Power Supply Selection
Q1: What are the top priorities when selecting power supplies for medical devices?
A1: Three core factors shall be prioritized:
- Safety certifications: Products must comply with IEC 60601-1 and GB 9706.1, preferably with TUV and CB certifications;
- Leakage current and insulation grade: Choose CF-grade for cardiac-related devices and BF-grade for conventional medical equipment;
- Operational reliability: Select products with MTBF over 100,000 hours and low failure rate.
All series products of Zhuhai Xinhe Power Supply fully meet the above standards and provide professional customized selection guidance.
Q2: How to match power supplies for medical devices of different power ratings?
A2: Match power supplies according to rated power and peak power of devices:
- Small portable devices (portable monitors): 5W-30W, recommended XH-PG series miniature modules;
- Medium-sized medical devices (B-ultrasound scanners, infusion pumps): 30W-200W, recommended XH-PS series standard modules;
- Large medical equipment (hemodialysis machines, CT auxiliary equipment): 200W-1000W, support customized high-power power supplies with fast sample delivery.
Q3: What impacts do medical power supply certifications bring to medical device manufacturers?
A3: Valid power supply certifications are essential prerequisites for medical device market access. Devices equipped with uncertified power supplies cannot pass NMPA medical device registration, EU CE certification and US FDA certification.
Fully certified products from Zhuhai Xinhe Power Supply can be directly matched with exported medical equipment, shortening certification cycles and cutting compliance costs effectively.
