TDK LAMBDA MU4 series of 1U high power supplies feature very low acoustic noise and BF-ready medical isolation, and can provide 600W with an input of 85 to 264Vac (derate below 90Vac) and 800W with a 180 to 264Vac input. Up to five fully isolated output voltages can be easily configured using product’s on-line quick product finder. A patented intelligent fan speed control circuit uses a microcontroller algorithm to monitor the temperature of the primary converter and each individual secondary module. This enables the speed of the fan to be accurately adjusted and optimized to provide an audible noise as low as 36dBA, even with an 80% load. A low noise level improves patient comfort and reduces operator fatigue.
