MEAN WELL UHP-500R-5 Switching Power Supply 5V DC, 400W, 80A Output, Chassis Mount, Fanless Design UHP-500R-5

MEAN WELL UHP-500R-5 Switching Power Supply is a rugged, slim, and highly efficient power supply unit delivering 5V DC output at 80A with a power rating of 400W. Designed for chassis mounting, this fanless, convection-cooled unit provides silent and reliable operation within an operating temperature range of -20°C to +70°C.

Incorporating an active PFC function, it ensures enhanced power factor and compliance with international standards including BSMI CNS143361, CCC GB4943.1, CSA C22.2 No. 62368-1, and UL 62368-1. The power supply supports input voltages from 90V AC minimum to a maximum of 370V DC and provides robust protection against short circuit, overload, over voltage, and over temperature conditions.

The unit’s slim 31 mm depth and compact form factor (dimensions: 232 mm length, 81 mm width) make it suitable for tight electronic installations. It is built to withstand surge inputs of 300VAC for 5 seconds, ensuring resilience in industrial environments.

Additional features include a DC OK active signal, optional redundant function for increased reliability, and an LED indicator for power-on status. Capable of operating at altitudes up to 5000 meters, it is ideal for industrial automation machinery, control systems, mechanical and electrical equipment, electronic instruments, and LED display applications.

High efficiency up to 90 percent ensures energy savings. Fanless design eliminates moving parts, enhancing operational reliability. Wide operating temperature range from -20°C to 70°C accommodates harsh environments. Built-in active PFC reduces harmonic emissions and improves power quality.

Surge input protection supports 300VAC for 5 seconds. Comprehensive protections ensure safety under fault conditions. DC OK and redundant functions enable system monitoring and fault tolerance. Slim, low-profile chassis mount design supports space-constrained applications.

Suitable for industrial automation, control systems, electronic equipment, and LED displays. Certified to multiple international safety and EMC standards.
