Alternators meet the requirement of BS EN 60034 and the relevant section of other international stan-dards such as BS5000, VDE 0530, NEMA MG1-32,IEC34, CSAC22.2-100, As1359, and other stand-ards and certifications can be considered on request.The 2/3 pitch design avoids excessive neutral currents. With the 2/3 pitch and carefully selected pole and tooth designs, ensures very low waveform distortion.Brushless Alternator with brushless pilot exciter for excellent load response.The insulation system is class H, easy parallelling with mains or other generators, standard 2/3 pitch stator windings avoid excessive neutral currents. Backed by worldwide service network.

(General functions and features)

Control screen is small, reliable performance, simple operation, the internal circuits clear, easy detection. With automatic detection and protection features so as to protect the engine safe and stable operation. Multi-interface display unit work and alarm state, intuitively clear, LCD displays the parameters of Diesel Engines. Microcomputer can be set on the control panel input, output, alarm, delay and other parameters. Maintenance, manual, automatic and other modes of operation. No non-normal electricity supply automatic starting, generator fault protection off, to provide historical state records. Generator over / under voltage, generator frequency / high frequency generator speed due to speed / overspeed, low oil pressure, high temperature, emergency stop, battery over / under voltage, over current / short circuit protection function.
