Mobile Power Supply Unit (MPSU)

LSI designs and produces MPSUs for the U.S. Army UH-60 Black Hawk Maintenance Trainers (BHMT-Ms) and Chinook Helicopter Maintenance Trainers (CHMTs).  The MPSU is powered by 3 phase, 208 or 220 VAC at 200 Amps and produces 3 phase, 400 Hz, 115 VAC at 30 KVA and 60 Hz power, and 120 VAC to the helicopter.  It also produces 3000 psi hydraulic press at 6 to 15 GPM using a Variable Frequency Drive.  The MPSU is very quiet in operation to facilitate instruction on the hangar floor.
