This kit is a quick, neat, and inexpensive way to provide a smoothed ±25V, 2A dual polarity unregulated DC power supply suitable for powering many audio power amplifiers.
The kit comprises four IN5401 (100V/3A) diodes in a standard bridge rectifier set-up and four 2200uF/50V electrolytic capacitors which provide DC ripple smoothing. They are mounted on a small PCB to avoid the usual spaghetti-wired mess.
It only requires the AC output of a centre-tapped transformer (not supplied). See the kit documentation for information on choosing an appropriate transformer for your needs.
Product selection advice: Please ensure the equipment under power draws less current than the power supplies maximum rated current detailed below (do not rely on equipment rating specifications as they are often incorrect). We recommend that the power supply is rated at least 20% above the equipment to be powered so it can handle current surges, etc.Specifications
