Featuring the same power module, microprocessor and LCD as the LDS® SPA-K range, this amplifier has been optimized to drive our low-force shakers LDS® V650 and V780 shakers, enabling them to impart higher forces than when paired with other units.

With a Class-D rating, it offers maximum power with minimal energy waste and lower running costs. LDS® HPA-K is designed for centralized operation, allowing you to start up the amplifier, monitor its power output and interlocks, and shut it down, from the same PC that hosts the vibration controller.
