Power amplifier

Unholtz-Dickie's SA Series Power Amplifiers extend the life of existing shaker systems by replacing the original amplifiers. These 100% air-cooled units are more than 90% efficient, and take up less than half the floor space as the original water-cooled amplifiers. They typically provide at least 10% more random vibration performance and 50% more shock performance than a comparable linear amplifier. Standard features include extensive electromagnetic interference shielding, three-phase line filtering, a full-featured control panel, and safety interlocks. Output ratings from 15 to 480 kVA are available to drive shakers made by a variety of manufacturers.
