Description

Laboratory power supply, integrated in a PC. Goal is to fit it in an case from a CD reader and have outputs mounted outside for easy access, programmable control/read of its outputs via serial over USB interface. Target - supply power from a 4-pin molex and convert to independent fused outputs: adjustable, 12V, 5V with option to enable/disable, read voltage and current. At least 2A each. Adjustable output should have range of about ~2-24V. In addition we can have a couple of digital outputs for controlling external devices. No isolation - the idea is to control devices that are already connected to the same PC in some way.
