The LW160.141-60 system utilizes the Labworks MT-160 thruster and PA-141 linear power amplifier to form our highest performance dedicated modal test system. The thruster's full 1.4 inch stroke capability, low suspension spring rate and light-weight armature makes this system ideal for most modal test applications. The thruster body features a through hole, and a single collett or thread load attachment to accommodate both tension wire and stinger modal testing. The PA-141 amplifier is direct coupled to the shaker to give the maximum performance at DC through high frequencies and can be easily switched from voltage source mode to current source mode for force input testing applications. The voltage-proportional-to-current amplifier signal output facillitates servoed force test operation. Dual bar graphs display the system operating levels and internal and external interlocks help protect the system from accidental abuse.
