SEW 590/630 Series
The SEW 590/630 Series of Shakers are matched with the DSA 320K Series of Power Amplifiers. Its armature supply is assembled in three 19-inch network racks of 36 unit height and field supply is assembled in two 19-inch network racks of 36 unit height. The water cooling system is assembled in two 19-inch network racks of 36 unit height. All three system communicate with each other over a galvanically isolated RS 485 interface.
