Description
The renewed ULPS2250B is an Ultra Low Noise High Performance Linear 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’s a good choice for those applications that need ultra low noise and high precision outputs like Audio, RF, Medical, Instrumentation, Quantum Computing, Optoelectronics, High Precission Data Converters and so on.
ULPS2250B is also available with Aluminum case and accesories. Check it out here.
