This power control house was built faster than all the other major components in what will be the final test stand. Inside are a set of panels consisting of a 18-pulse rectifier and a set of 4 parallel bridged drives that operate a 2000 HP 3000 Base/ 6000 maximum and a 250 HP Tail rotor motor that load the transmission based off applying torque to the two 1000 HP 3000Base/6000 Maximum motors that replicate the jet engine inputs. Total HP of the system is 4,250 hp, but power is re-circulated such the 2000 HP transmission test is achieved with about 600 KW of continuous power input.

The engines required as much input as possible, to accommodate growth and future up sizing while still meeting Category 2 arc flash safety standards. The safety concerns of the government were met by supplying a Y-Y-Y transformer which reduced the short circuit input current from 34 KA to 7.7 KA. An integrated E-stop circuit provide a powered stop. We take pride in building state of the art systems using Ethernet communications from the dyne controller, and achieving industry leading performance at a price competitive with controllers of much lower performance expectations.
