Fanless 750W AC-DC Power Supplies Support Quiet, Reliable Operation in BF-rated Medical Equipment
XP Power has introduced the UCH750 series, a line of 750W convection-cooled AC-DC power supplies. These compact, chassis-mount units are designed for noise-sensitive medical and industrial equipment, distinguishing themselves as one of the few fanless medical power supplies available at this power level.
The fanless design of the UCH750 series directly addresses the growing demand for quiet operation in critical environments such as medical imaging, patient monitoring, diagnostic instruments, and home healthcare devices. By eliminating the fan, the series not only removes a source of noise but also a common component prone to wear, thereby contributing to reduced maintenance requirements for equipment designers.
Furthermore, the UCH750 series is engineered to meet the stringent requirements of BF-rated medical equipment, which is increasingly prevalent in hospital settings. It provides 2 x MOPP isolation between input and output and maintains a maximum patient leakage current of 100µA, ensuring essential patient protection and low leakage current. Achieving up to 96% efficiency, the series also minimises conversion losses and internal heat generation.
