These units are intended to replace discontinued LDS® amplifiers that were used to drive older air-cooled shakers, whether LDS or other.

Brüel & Kjær offers a wealth of experience in designing power amplifiers to match most shakers available or in operation today. This includes supplying amplifiers to meet the requirements for specific tests that may not be possible with off-the-shelf units. All requests are reviewed by our in-house Special Projects team, who then recommend the solutions that best suit your needs.
