The dLW139.153-75 is our strongest permanent magnet field shaker system. Capable of up to 75 lbs.sine and full 50 lbs-rms random force, the 3-inch diameter armature table is suitable for larger loads that require high vibration levels. The shaker's full 1-inch armature stroke capability is ideal for many modal as well as low frequency general applications. The air cooled dPA-153 dLAB shaker amplifier delivers full system performance while minimizing power and amplifier cooling requirements. The amplifier's multi-function digital display provides amplifier operational status as well as system peripheral and complete vibration system operational diagnositcs. Built in shaker-specific current limiting and full internal, system and external electrical interlock connections and logic help protect the system and test specimen from accidental abuse. A guided flexure table base system is available for larger or heavier loads and loads with a higher center of gravity.
