UHP-750/1000 Series Fanless Power Supplies


UHP-750/1000 Series Fanless Power Supplies

MEAN WELL's UHP series fanless conduction-cooled power supplies are expertly designed utilizing superior silicone potting compound and potting procedures.

The unique fanless and semi-potted design solves the user’s headaches regarding fan failures. The UHP-750 and UHP-1000 utilize a fanless design and are semi-potted with top-grade silicone gel to minimize the risk of failure. The potting procedure also includes extra steps to prevent air bubbles and ensure the silicone gel perfectly fills the space beneath the PCB and components. Although these extra steps increase the production cost and time, the prevention of air bubbles ensures the best production consistency and thermal conduction performance. Fanless design can also solve fan noise level issues, thus making the UHP series extremely suitable for environments that require absolute quiet.

UHP-750 and UHP-1000 provide multiple cooling options so users can flexibly design-in the power supplies based on their system’s needs. The cooling options include either mounting the power supplies on a 450 mm x 450 mm x 3 mm metal plate or adding external fans to cool the units. These two cooling methods allow the power supplies to output at the maximum rated wattage levels. If there are space limitations, the UHP-750 and UHP-1000 can still output up to 70% of the maximum rated power thanks to the ultra-high efficiency of 96% and superior mechanical designs. By providing multiple cooling options, the UHP-750 and UHP-1000 can be seamlessly integrated into all kinds of application environments for maximized flexibility of system designs.

The UHP-1000 is equipped with programmable voltage (PV) and programmable current (PC) functions. By applying external DC signal voltages, the output voltage can be modulated between 50% to 120% of the rated voltage, and the output current can be modulated between 20% to 100% of the rated current. The PV and PC functions allow the UHP-1000 to power different types of loads and to satisfy different control requirements for powering burn-in equipment, charging stations, and laser systems.

Other key features of the UHP-750 and UHP-1000 include compliance to the EN60335-1 household safety standard, which is uncommon for such high-power products; wide operating temperature range of -30°C to +70°C, which allows unrestrained use in extreme temperature environment; and a low-profile of only 41 mm height, reducing the difficulty to mount the power supply into the end equipment. These features make the UHP-750 and UHP-1000 outstanding power solutions for industrial control systems, electromechanical industries, and communication apparatuses requiring high performance, small form factor, and fanless operations.
