Quad Bench Power Supply

To the right of the output Johnson
posts are the switches that set the
polarity of the floating supplies—as
well as the switch that disconnects all
power supply outputs—while leaving
the unit still powered up.

The need for a bevy of equipment for building and testing presents a problem: how to deliver an adequate power supply while keeping workbench clutter to a minimum. Brian decided to tackle this classic engineering conundrum with a small, low-capacity … Continue reading
