Simple Universal Laboratory Power Supply Circuit Diagram

This is the Simple Universal Laboratory Power Supply Circuit Diagram. The value of the design lies in the use of IC1, an LM317HVK adjustable s.eries-pass voltage regulator, for broad-range performance remainder supplies voltage-setting and current-limiting functions. 

The input to ICI-comes from the output of BR1, which is filtered by CI and C2 to about +60 Vdc, and the input for current-sense comparator IC2 comes from BR2, which also acts as a negative bias supply for regulation down to ground.
