The Mean Well UHP-500R-48 is a 502W AC/DC power supply from the UHP-500 series, designed as a single-rail enclosed unit. It provides a nominal 48V output and operates with a rated current of 10.45A.
This power supply features a universal AC input range of 90-264VAC, making it suitable for global applications. It boasts high efficiency, reaching up to 95%, and includes active power factor correction (PFC). The unit is designed for chassis mounting and has a slim, low-profile form factor with dimensions of 232.0mm x 81.0mm x 31.0mm.
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 fanless design makes it ideal for environments where dust or damp air is a concern. The UHP-500R-48 can withstand a 300VAC surge for up to 5 seconds and operates within a temperature range of -20°C to 70°C with derating.
Key features include adjustable output, PFC, and universal input. It has a single output and is approved by multiple agencies including CB, CCC, CE, cURus, EAC, and TUV. The redundancy option allows for parallel connection of two units for failover.
The UHP-500R-48 has a nominal output voltage of 48V.
The UHP-500R-48 has a power rating of 501.6W.
The UHP-500R-48 can provide a maximum current of 10.45A.
The UHP-500R-48 has a typical efficiency of 95%.
The UHP-500R-48 accepts a universal input voltage range of 90 to 264VAC.
The UHP-500R-48 operates between -20°C and 70°C, with derating applied outside this range.
The UHP-500R-48 is fanless and cooled by conduction, requiring mounting on a suitable aluminum plate.
