Information about the MEAN WELL UHP-200R-3.3

The MEAN WELL UHP-200R-3.3 is an ultra-slim 200 W switching power supply built for applications that require very low output voltage with high current delivery. Delivering 3.3 V DC at 40 A, this model is especially well suited for industrial control systems, communication equipment, embedded electronics, and test and automation environments where stable low-voltage power must fit into restricted installation spaces. Its remarkably low profile of just 26 mm, combined with a universal input range and active PFC, makes it a strong choice for compact and globally deployable power designs.

Its standout advantages include a built-in redundancy function for parallel operation of two units, a DC OK monitoring signal for reliable system feedback, and a fanless convection-cooled design that supports quiet, low-maintenance operation. The unit also provides comprehensive protection against short circuit, overload, overvoltage, and overtemperature, and it is designed for thermally optimized installation on an aluminum plate or metal chassis. This makes the UHP-200R-3.3 a high-reliability solution for demanding systems that prioritize high current capability, low installation height, industrial robustness, and improved operational security.
