SEW 590 Series

The SEW 590 Series of Shakers are matched with the DSA 200K and DSA 240K Series of Power Amplifiers. The Power Amplifier of a Water Cooled System is made in two parts: Armature Power Supply which houses the DC Section, Control Section, and Power Module for the Armature Coil and Field Power Supply which houses the DC Section and Control Section for the Field Coils. A dedicated Water Cooling System which pumps distilled water through the Shaker as its primary path and uses cold water from a Chiller as its secondary path with heat exchangers to cool down the distilled water of the primary path is also provided. Everything is assembled in 19-inch industrial rack of 36-unit height.
