ULPS2250BI – 50VA Dual Ultra Low Noise Linear Power Supply

Description The ULPS2250BI 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. The main difference between ULPS2250B and ULPS2250BI is the diode bridge rectifier section, which has been replace by an Ideal Bridge Rectifier using MOSFET Technology, which increases the performance and reducess the heat loss. 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. ULPS2250BI is also available with Aluminum case and accesories. Check it out here.
