The KRD20 series pneumatic bump test machine replaces the traditional mechanical cam-type crash bench and is suitable for repeated impacts on electronic components, equipment and other electrical and electronic products during transportation or working. 1. Fully pneumatic driven, clean and environmentally friendly, good repeatability and high reliability. 2. Control the frequency of collisions by adjusting the gas pressure to achieve continuous high-frequency collisions. 3. Test time and collision frequency can be set arbitrarily, and it will stop automatically after the test is completed 4. The controller has door protection, over speed protection and zero signal protection to ensure the safety of the system. 5. The drop height is adjustable, only need input the overload value; adaptive adjustment of the collision process to ensure the repeatability.
