The ULPS1225B is an Audiophile High Performance Power Supply. It includes input EMI Filter, attenuating all types of interferences from other devices attached to the line. Output stage performs a ultra low noise, ripple and dropout voltage.
It can handle up to 8x Raspberry Pi 4 at 5V streaming music, although we recommend to not reach the PSU limit for a better thermal and DC output performance.
It’s also a good choice for those applications that need ultra low noise and high precision outputs like RF, Medical, High Precission Data Converters and so on.
