18W Medical Power Supply | Compact AC-DC Embedded Module for Medical Devices

The 18W medical power supply is a compact AC-DC embedded power module designed for low-to-mid power medical electronic systems requiring stable, safe, and efficient energy conversion. It is widely used in portable and handheld medical devices where reliability, size, and safety are critical design constraints.

Compared with lower power modules, the 18W solution provides additional power headroom for more complex medical devices that integrate multiple sensors, display units, and communication interfaces. It is commonly used in systems that require continuous operation and stable DC output for sensitive electronics such as microcontrollers, analog front-end circuits, and wireless modules.

This power supply is designed with medical-grade isolation and low leakage current considerations, making it suitable for patient-connected or near-patient equipment environments depending on system integration. It supports PCB-based embedded installation, allowing direct integration into compact medical device architectures.

Typical applications include SpO2 monitoring systems, handheld ECG devices, portable diagnostic tools, and home healthcare monitoring equipment.

This product is part of our medical power supply solutions portfolio, covering a full range of AC-DC medical-grade power modules from 12W to 120W. OEM customization such as output voltage, mechanical structure, and certification support is available via our custom medical power supply services page.
