AC/DC Power Supplies

This section includes all programmable power supplies powered by single-phase or three-phase AC, which deliver DC at a programmable voltage. Some can only deliver power from the AC grid to the DC load, and are designated "unidirectional" in the submenu; while "bidirectional" power supplies can deliver or recover energy from regenerative loads to the grid. Almost all power supplies always deliver the same polarity to the load; some may offer multiple output channels.
