Output 13.8 volts at 20 amps. This is a power unit I used for a special project and I have now fitted an original ICOM radio power lead with connector. The power supply benefits from additional terminal outputs for powering extra small station accessories (in addition to one transceiver) or as a standalone bench top supply. A linear power supply of this type can be much better than later switched-mode units because it generates no rf hash! Professionally adapted: see internal photos.
