4000 Kgf Vibration System

The Hi-range of Shakers is designed for critical tests in Automotive, DRDO and Avionics. The customer’s continuous duty test is the most unique feature in this category.

Automatic pneumatic operated load compensation system employs latest micro-electronics & optical sensors built into the shaker which helps in realising nominal displacement at all payloads.

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.
