The Mean Well USA UHP-350R-3.3 is a 198-watt enclosed AC/DC power supply designed for reliable operation in various applications. It provides a stable 3.3V output voltage at up to 60A current, with an efficiency rating of 88.5%. This unit features a universal AC input range of 90-264VAC, making it suitable for international markets.
The UHP-350R-3.3 is designed with a fanless, enclosed form factor for quiet operation and to prevent dust or moisture ingress. Cooling is achieved through conduction by mounting the power supply onto a suitable aluminum plate, which can also serve as part of the enclosure. This design makes it ideal for environments where traditional fan-cooled power supplies might fail prematurely.
Key electrical specifications include adjustable output, active power factor correction (PFC), and a high isolation voltage of 3.75 kV. The operating temperature range is -30°C to 70°C, with derating applied at higher temperatures. Its dimensions are 220.0mm in length, 62.0mm in width, and 31.0mm in height, suitable for chassis mounting.
This power supply is approved by major agencies including CB, CCC, CE, cURus, and TUV, ensuring compliance with international standards. It is suitable for applications in household appliances and ITE (Commercial) equipment.
