Different alternator type (frame) is corresponding to different power, clients always choose alternator power according to total power of its load. Clients should know alternator load characteristic and size thoroughly. It should consider special load independently.  Generally, kW is presented in the form of power, and three-phase alternator factory capacity is calculated according to rated power factor 0.8 before our alternator goes out. That is kVA=kW/0.8. In most cases, we give the two following kinds of power according to every type al...

Alternator efficiency is the ratio of output kilowatts (electrical energy) to input alternator mechanical work. That is:    Prime mover outputing mechanical power should be greater than or equal to alternator input power. Alternator input power except connecting efficiency of diesel engine and alternator, should be the minimum output power of diesel engine. The alternator efficiency is different under different voltage and load, and specific conditions can contact Kungfu company!
