Description The ULPS1225A 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 RF, Medical, Instrumentation, High Precission Data Converters and so on. ULPS1225A is also available with Aluminum case and accesories. Check it out here. For a lower Ripple Noise and Higher PSRR, check out the ULPS1225B. Key Specifications – Ultra Low Noise Output Ripple – Talema Audio Grade low-leakage Toroidal Transformer – MUR860 Ultrafast Diodes (For a warmer sound) – Dual /- Outputs (Can be combined in Series or Paralel) – Ultra low dropout voltage – Slow Output Charge/Discharge (Avoiding “pops”) – Inrush current limiting – 115/230V Selectable – RC and LC Input and Output Filtering – Top Brands Components (Murata, Bourns, TI, Nichicon,…) – Designed and hand assembled in the beautiful Barcelona, Spain We only use original parts and from top brands on our products.
