Have you experienced fan failure when using power supplies in a dusty environment? Have you been troubled by the loud noise from fans in power supplies? Have you had difficulty finding a low-profile power supply to fit behind display signs or narrow space? Have you looked everywhere on the market but cannot find a suitable power supply with household safety compliance? In an effort to provide solutions to the aforementioned issues, MEAN WELL is proud to unveil the fanless conduction-cooled power supplies, the UHP series. With over 35 years of experience in switching power supply design, MEAN WELL’s R&D team expertly designed the UHP series and utilized superior silicone potting compound and potting procedures. The UHP is truly the golden standard for fanless power solutions in the market.
Ever since the conduction-cooled UHP-200/350/500 series were released a little over one year ago, MEAN WELL has shipped over 200 thousand units worldwide and received a multitude of positive feedback from the market. Not to mention the fact that many customers expressed great interest in the products even when they were still being developed. Now, MEAN WELL expands to higher power coverage by releasing the UHP-750 (750W) and UHP-1000 (1000W) series. Undoubtedly, the UHP-750 series and UHP-1000 series will be the top choice for high-power power supplies that are suitable for applications in a wide variety of environment.
Why did the UHP-750/1000 series receive so much traction from the market? This is due to the unique design: fanless and semi-potted, which solves the customer’s headaches regarding fan failures. Some equipment requires an uninterrupted operation and may be installed in locations that are difficult to access. Some applications even install external monitors for fans, thus increasing the design difficulty and cost. In order to minimize the risk of failure, UHP-750/1000 utilizes fanless design and is semi-potted with top-grade silicone gel. The potting procedure also included extra steps to prevent air bubbles and to 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 environment that requires absolute quietness.
UHP-750/1000 provides multiple cooling options so customers can flexibly design-in the power supplies based on their system’s needs. The cooling options are either mounting the power supplies on a 450x450x3mm 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-750/1000 can still output up to 70% of the maximum rated power thanks to the ultra-high efficiency of 96% as well as superior mechanical designs. By providing multiple cooling options, the UHP-750/1000 can be seamlessly integrated into all kinds of application environments, thus maximizing the flexibility of system designs.
The UHP-1000 is also equipped with Programmable Voltage (PV) and Programmable Current (PC) functions. By applying external DC signal voltages, the output voltage can be modulated between 50%~120% of the rated voltage, and the output current can be modulated between 20%~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, thus making it suitable for powering burn-in equipment, charging stations, and laser systems.
Other key features of the UHP-750/1000 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; low-profile design with only 41mm height, which reduces the difficulty to mount the power supply into the end equipment. Combining all of the great features above, the UHP-750/1000 will be outstanding power solutions for industrial control systems, electromechanical industry, and communication apparatuses that require high performance, small form factor, and fanless operations.
