Production of power supplies for medical devices and equipment in mainland China also spotlights development of ultrasmall, lightweight and energy-saving types.
Mainland China manufacturers of medical-use power supplies keep high product reliability and safety a priority. They ensure conformity to IEC 60601, EN 60601, EN 55022 and UL 60601 standards, in addition to CE, UL, and DOE Level V or VI. There are releases that follow the MOPP and 2xMOPP requirements.
Companies are likewise developing smaller and more lightweight versions with energy-saving features as demand for portable medical devices rises.
The mainstream selection includes open-frame and desktop types for hospital use, and wall-mount kinds for home use. The units have 3.3 to 48V rated voltage and 5 to 600W rated power.
The key manufacturing inputs used include chips, PCBs and passive components. The first is usually from foreign companies such as TI, ADI, Renesas and ON Semiconductor. Some makers turn to local chip providers, including Silan and Shanghai Belling. The rest of the components and materials come from the domestic supply unless customers specify other sources.
Input and labor costs climbed in the past year, prompting some companies to increase their prices between 5 and 10 percent. The majority, however, kept quotes flat to stay competitive. In the year ahead, expenditures are expected to stabilize and keep prices unchanged.
The products in this gallery have been handpicked by our market analyst for representing current trends in power supplies for medical equipment from mainland China and Taiwan makers.
