Linear Power Supply Recommendations!


While I realize linear power supplies share the same basic principle—using a transformer to step down voltage, rectification to convert AC to DC, and regulation to maintain a steady output….there are several factors that ultimately differentiate their performance in a specific application. 

Did you find one particular LPS performed better than the others?  I am looking for a dual output 12V / 3A power supply to power my Telegartner Opt Bridge 1000M. 

Ferrum HYPSOS Dual Output with its ‘Sweet Spot Tuning’ has caught my attention. Any users out here that is currently using this LPS?

Teradak and LHY good options, not crazy expensive. There are many more expensive options. Like anything, find a good match for the level of the rest of your gear. At some point, diminishing returns.

There are multiple options available for <$150 USD that provide solid voltage regulation and filtering with measurable ripple being <10μV and usually half that or less. That won't prevent some from making this exercise seem more expensive and extract whatever the HiFi market will bear, but that should be expected. This recent video should prove both interesting and useful:
