The low range of Shakers is designed for educational instaurations, experimental purpose and to test small components, PCBs and light weight capacity components.
As a standard configuration, the shaker is supported on a frame. It is force-air-cooled by a Centrifugal Cooling Blower with silencer is used to suck hot air from shaker via flexible hose pipe and is interlocked with the amplifier for operational safety.
The shaker's moving element are energized by the direct current and alternating current supplies respectively generated and are electronically interlocked to the power amplifier.
The Digital Switching Power Amplifier having the in-built intelligent microcontroller based control unit is housed in a table top movable rack console. It has a feather-touch user-friendly interface control panel at the front panel of power amplifier to drive the Electro-dynamic Shaker.
