Power Current Limiter 13v 20A Circuit

This PSU has long been particularly created for current-hungry ham radio transceivers. It delivers safely around 20Amps at thirteen.8V. For reduced currents, a separate existing limiting output, able to 15ma as much as a total of 20A has long been extra. [...]
