Shakers & Exciters
LDS DPA-K Power Amplifiers
Specifically designed to supply LDS® V900 high-force shakers with the signal they require to perform at optimal levels, these amplifiers combine strength, efficiency and adaptability. Featuring a Class-D rating, they deliver maximum power with minimal energy waste and lower running costs. Compatible with third-party vibration systems and suitable for multi-shaker applications, LDS® DPA-K amplifiers are modular and scalable, allowing you to easily and economically increase their power capacity to meet future needs without having to replace the entire unit.
