Kepco MAT are linear power supplies that are oriented to systems applications. Their principal control means is a 2-wire, long range, serial bus, Kepco's single address, multiple instrument bus. As many as 27 power supplies, including models in the Kepco MST, MBT and BOP series may be "daisy-chained" on this bus and interfaced either to IEEE 488.2, a PC bus, or to a VXI host.
