Arduino Controlled Power Supply

Thoughts on a power supply with three relays in it controlled by an arduino to set the output voltage. Say 3.3v, 5v. and 0 - 15v.

  • Hi Tyler,

    Sometimes relays are used in power supplies to adjust the input power (select transformer taps) to the regulators so that the regulator doesn't have to dissipate too much power due to the difference between input voltage and output voltage. It will be interesting to see your schematic.
