The innovative G-075-039 DC generator system is a 3.5 kW alternator with regulation unit, ideally suited for aviation applications.The G-075 offers maximum performance and efficiency because of its unique power-to-weight ratio. It has option of synchronizing two units to operate in parllel.The regulator delivers a pulse width modulated field control at constant frequency and includes two separate independent regulation circuits. Each regulation circuit has a separate, independent power circuit and each one is controlled by a separate controller.In a two-generator system, current sharing in parallel mode is within 10% of generator rating. The G-075 system is uniquely suited for avionics and other special applications due to its redundancy and robustness. The G-075 is designed to meet aviation & MIL standards and has been tasted and proven in the field.
