Marathon

MP series alternator coupled with diesel engine can be used for for all occasions, also can be used as emergency power supply. MP series generator unique design, advanced structure, excellent performance, reliable operation, easy to use, available for all the application. The technology of Marathon is the reprentative of international advanced level.

Excellent electrical performance
1). Steady state voltage rate 1% or less 
2). The state pressure regulating rate + 20% - 15% Un (60% In. Cos φ ≤ 0.4 lag)
3). Voltage regulating range > - 10% of the Unbalanced
4). Line pressure waveform sine form distortion rate < 5% 
5). Thermal deviation is zero

Unique structure design
1). Alternator is full protection structure, internal ventilation cooling structure, aluminum alloy fan, ventilation rate is high, low temperature rise.

2). Brushless excitation mode, with solid state voltage regulator, voltage regulator with low speed protection, electromagnetic interference suppression, excitation shut off, and other functions, and with stability control and voltage amplitude adjustment. 


3). The structure is salient pole rotor structure, damper winding and rotor core even become an organic whole, field winding used thermosetting epoxy filling, have high mechanical and electrical strength.
4). Rotating rectifier is located in the exciter rotor outer, easy to maintenance.
5). The box capacious, It can add various devices. The box is located in stand behind above, compact appearance.
6). Insulation class is class H.
7). Per the request of customer, synchronizing control modular is optional.
