Choose a suitable medical-grade AC-DC power supply that not only matches the power and voltage, but also needs to meet the IEC 60601-1 standard, strictly control low leakage current, and satisfy the highly reliable requirements of the clinical environment. UE manufacturers provide desktop, wall mount, open frame, and USB-PD power supply products -IEC 60601-1 certified, 5W-1000W, custom DC output on request.
External medical power supplies include two types: desktop power adapters and wall-mounted power adapters, the most widely used AC-DC power solutions for Class II medical devices. DC output is stable, low ripple, leakage current ≤100μA at 264VAC worst-case input, meeting IEC 60601-1 3rd/4th edition requirements.
Open-frame-type medical power supplies are the ideal choice when the device design requires the power supply to be directly integrated into the system's internal components. Also available in an enclosed configuration with metal shielding for dustproof and EMI-resistant applications. Suitable for medical imaging equipment, laboratory analyzers, and rehabilitation training equipment.
Enclosed medical power supply uses a metal shielding enclosure with internal EMI filtering, providing dustproof, moisture-proof, and EMI-resistant power solutions for medical devices. Suitable for fixed medical devices, surgical systems, and BF-rated applications with strict electrical safety and EMC requirements.
The common USB charger is not designed for the medical environment. The medical USB power supply must meet IEC 60601-1 leakage current and isolation requirements — essential when powering bedside tablet terminals, wearable monitoring devices, or ward entertainment systems.
Choosing the right medical-grade AC-DC power supply is not just about matching the wattage and voltage. The key to affecting the choice type’s core factors is installation method, mechanical form factor, enclosure type, and output interface. These decide how to combine the power supply and your device’s design. The table below compares UE’S four medical power supply configurations across the parameters that differ most between types.
| Parameter | External | Open Frame | Enclosed | Medical USB |
|---|---|---|---|---|
| Power range | 24W – 310W | 15W – 500W | 60W – 500W | 23W – 240W |

Summary and Selection Guide:
UE all series meet IEC 60601-1 strict requirements, which guarantee low leakage current, and provide high-performance medical-grade power supply assurance.
Choose the medical power supply needed from three core parameters: output voltage, wattage, and form factor. Whether you need a medical-grade 12V power supply for a portable device, a 24V medical-grade power supply commonly used for diagnostic equipment, or a 500W medical power supply for a high-power consumption system. You can make sure the required specification combination through the sheets below.

For the engineer of medical devices, the power supply specification sheet is just a start. The actual performance under load conditions, thermal stress, and long-term operation is what determines whether your device achieves the clinical reliability standard. UE GaN-based design achieves up to 93% efficiency — 8–12% higher than conventional silicon solutions, enabling 30% volume reduction at equivalent power output.
The standard test before the Ex-factory is a bottom line, not an end. For the engineer of a medical device, the true problem is: Can this power supply still maintain stable performance after operating for thousands of hours in a clinical environment?
UE medical power supply’s verified system is far more than the common ex-factory quality inspection. Each medical PSU is 100% full load aging test as a standard production process. Before the assembly line, screening out early-life failure risks in advance.MTBF >200,000 hours calculated per MIL-HDBK-217- a methodology-traceable figure that can be directly referenced in your design documentation and certification submissions
Production verified process includes 4 stages:
For device engineers currently pursuing IEC 60601-1 certification or FDA 510(k) submissions, a power supply backed by complete, traceable test data can directly reduce system-level compliance workload system-level compliance work and provide a clear audit basis for your QA team.
Electrical isolation is a basic safe requirement of medical power supply design. UE medical isolated power supply with 2×MOPP enhanced isolation design, dielectric withstand voltage between input and output reaches 4,000VAC, with creepage and clearance distances exceeding IEC 60601-1 requirements for double insulation. It meets IEC 60601-1 isolation verification required for BF rated patient contact applications.
For medical devices in direct contact with patients, leakage current is a core parameter directly related to patient safety. UE ultra-low leakage current design at 264VAC worst-case input — touch leakage current ≤100µA, 3× lower than the IEC 60601-1 enclosure leakage limit of 500µA, with no additional downstream filter components required, meeting BF rated application requirements.

As medical devices continue to trend toward miniaturization, the size of the medical power supply has become a key design limitation. UE high-density power supplies for medical applications deliver maximum power output within a minimal footprint. The compact open frame series is compatible with standard chassis slots and custom enclosures. Power density up to 0.718 W/cm³ — exceeding the typical 0.4–0.5 W/cm³ range of conventional medical open-frame designs, enabling 30%+ size reduction at equivalent wattage, covering 15W to 500W.

Design a compliant medical power supply, or select one for your medical device, that does not simply match the voltage and wattage. Medical power supply design must confirm the isolation level, leakage current limit, input voltage range, operating temperature, and compliance certification before bulk production. UE sorts out core medical power supply requirements, which need to be verified by the engineers in the design stage.
