400 Kgf Vibration System

The low range of Shakers is designed to cater to the generalised testing requirements of various segments of the industry, these shakers are manufactured with a high degree of precision.

The shaker’s electromagnet is energized by the solid-state field power supply interlocked electronically to the amplifier console and is placed within the console to save space.

The Solid State, MOSFET/IGBT based, switching type, air cooled, matched with shaker to achieve the rated Sine, Random and Shock testing capabilities. Modular construction, Compatible with all standard Controllers.

Exemplary safety interlocks are logged on to the microcontroller based intelligent logic unit, which is most user-friendly in communicating the system status and operation.
