The LW163.151-25 system utilizes the Labworks MT-163 3"p-p thruster and convection cooled pa-151 linear power amplifier to form our lower force 3" permanent magnet field modal test system. The thruster's 3.0 inch stroke capability and low suspension spring rate makes this system ideal for many modal test applications. The thrusters armature features a through hole, and a single collett stinger attachment to accommodate both tension wire and stinger modal testing. The convection cooled PA-151 amplifier is direct coupled to the shaker to give the maximum performance at both low and high frequencies and can be easily switched from voltage source mode to current source mode for force input testing applications. The standard voltage-proportional-to-current amplifier signal output facillitates servoed test operation. Dual bar graphs display the system operating levels and internal and external interlock circuitry helps protect the system from accidental abuse.
