Specification:  Power input: 70-140VAC, (PMG, or auxiliary winding, single, three-phase).  Induction detection: 90-480VAC.  Large output: DC 12A 125V.  Protection function: built-in low speed, overexcitation, LAM, function.  Adjustment rate: better than 0.55.     Effect:  The generator is turning on the generator and uses the residual magnetism to send out a very weak voltage. This voltage is fed back to the generator's excitation coil to generate a stronger magnetic field and send out a high voltage, so that the voltage gradually grows higher. When the output voltage is higher than the set value, the excitation board will control the output voltage to decrease, and the excitation current will decrease accordingly. On the contrary, if the output voltage is not controlled or controlled at a small angle, the voltage will increase.     Package includes:  1 x R120 Diesel Generator
