ULPS1525B – 25VA Single Ultra Low Noise Linear Power Supply

Description

The ULPS1525B 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 can handle up to 3A Constant Current Source, although we recommend to not reach the PSU limit for a better thermal and DC output performance.

It’s a good choice for those applications that need ultra low noise and high precision outputs like RF, Medical, Instrumentation, High Precission Data Converters and so on.
