MEAN WELL Switching Power Supply UHP-350-3.3 3.3V DC 198W 60A Chassis Mount Fanless Design UHP-350-3.3

MEAN WELL UHP-350-3.3 Switching Power Supply is designed for reliable and efficient power conversion in industrial and commercial applications. With a precise fixed output voltage of 3.3V DC and a maximum power rating of 198W at 60A output current, this unit offers stable power supply performance for a wide range of electronic instruments and equipment.

The power supply features a chassis mount form factor with compact dimensions (220mm length, 62mm width, and 31mm depth), facilitating easy integration into constrained spaces. Its fanless design uses convection cooling, enabling silent operation while efficiently dissipating heat.

Robust operation is ensured with capability to withstand surge inputs up to 300VAC for 5 seconds. The build-in active Power Factor Correction boosts efficiency to 88.5% and supports operation from 90V AC to 264V AC input voltage range, and DC input up to 370V DC, suitable for diverse power sources.

Safety and reliability are prioritized with multiple built-in protections including short circuit, overload, over voltage, and over temperature, providing robust defense for the supply and connected devices. The power supply also includes a DC OK signal and an optional redundant function to enhance system monitoring and uptime.

Operating temperature between -30°C and +70°C and an altitude rated up to 5000 meters make it suitable for harsh industrial environments. The compact slim profile aids in installations with limited space.
