Engine Cooling Fan & SiC Controller The 1068000G1 is a 610 Vdc silicon carbide (SiC) based, air-cooled inverter and motor controller integrated onto an electric Engine Cooling Fan. The design utilizes GE’s SiC MOSFETs which enable an all-in-one Controller/Inverter/Fan solution, eliminating the traditional Fan with separate Motor Drive Inverter and its related coolant hoses and interconnecting cables. The SiC devices yield high power density and reduced size and weight for the cooling subsystem. Advanced thermal management technologies are employed to enable reliable operation in the high temperature environment. This Integrated Engine Cooling Fan solution allows the elimination of hydraulic motors and related pumps and hoses, or gear boxes and drive shafts in mechanically driven Fan solutions. Features: ♦ Best-in-Class SiC MOSFETs ♦ Digitally Controlled Operation ♦ Fault Reporting over CANBus ♦ High Efficiency ♦ Reduced weight versus Silicon ♦ High Reliability ♦ MIL-PRF-GCS600AVDC Input ♦ Overcurrent & Overvoltage Protection. ♦ EMI - MIL-STD-461F ♦ 90°C ambient air temperature ♦ Derating - NAVMAT-P-4855-1 ♦ AEC-Q101 SiC device qualification ♦ Submergible (up to 2 meters water) ♦ Nuclear Event Detection Electrical I/O: Physical: (See icd 1068001) Weight (Controller): 9.52kg (21 lbs.)
