Information about the MEAN WELL UHP-200R-4.2
The MEAN WELL UHP-200R-4.2 is a state-of-the-art 200W slim-type power supply specifically engineered for high-demand industrial environments where space is at a premium. Its remarkably low-profile 26mm design makes it an ideal choice for compact enclosures and shallow installations. This model stands out due to its fanless architecture, which relies entirely on natural air convection for cooling, ensuring silent operation and significantly reducing the risk of mechanical failure associated with moving parts. By utilizing built-in active PFC (Power Factor Correction), the unit maintains high energy efficiency and complies with strict harmonic current regulations, providing a robust 4.2V DC output at a substantial 40A current rating.
Distinguishing itself from standard models, the "R" version features an integrated DC OK active signal and a built-in redundancy function, allowing for parallel connection of two units to enhance overall system reliability and prevent critical downtime. It is built to withstand 300VAC surge inputs for up to five seconds and offers 5G anti-vibration capability, ensuring durability in harsh mechanical conditions. With broad safety certifications covering household appliances (EN60335-1) and IT equipment (EN62368-1), this power supply is a versatile solution for LED displays, industrial automation machinery, and electronic instruments requiring a highly stable, slimline power source.
