Detection and Power input: Voltage: **0~**4V ac ,single-phase second-line,

                           Frequency: *0/*0Hz,with copper jumper options;

Field Output: Voltage: **7V ac input,maximum *0V dc, Current: continuous

                         4A the non-continuously for *0 seconds, *0A,Resistance:

                          minimum *5Ω;

Voltage regulation: <±1%RMS(engine speed changes within 4%);

Voltage is established: in the AVR Input terminals need to remanence

                                 Voltage 5V ac above;

For external voltage regulation: The 1KΩ ,1Watt potentiometer when ±8%;
