Description: Product Description Features:* Brand new and high quality* The circuit of the R448 Automatic Voltage Regulator (AVR) provides closed loop control of the alternator output voltage by regulating the exciter field current. The voltage of the primary winding is proportional to the alternator voltage (characteristic shunt) and the voltage of the secondary winding is proportional to the stator current (composite characteristic: boost effect). It is supplied by two auxiliary windings of the voltage equalization circuit. The supply voltage is rectified and filtered before being used by the AVR monitoring transistor. Under PMG excitation, the permanent magnet generator (PMG) added to the alternator provides the AVR with a voltage of the main alternator winding. * Quadrature droop adjustment* AVR voltage adjustment* Stability adjustment* LAM threshold (underspeed) adjustment* Excitation upper limit adjustment* Single or three-phase selection** Voltage sensing* Normal or fast response time selection* 50 Hz or 60 Hz frequency option* Remote voltage adjustment option* LAM enable/disable option* Alternator frame selection* Excitation system selectionSpecifications:Part Name: Automatic Voltage RegulatorMaterial: ABS+MetalSize: StandardColor: BlackInput Voltage: 70-140V AC, (PMG or auxiliary winding, single phase, three phase)Reaction Measurement: 90-480V ACMaximum Output: DC 10A 125VFunction: Built-in underspeed, overexcitationLAM,Regulation: +/-0.5%Application;Applicable to Alternator LSA R448 for 42.2, 43.2, 44.2, 46.2, 47.2, 49.1.R448 V50 for alternator LSA 50.2Compatible with: for SHUNT, for AREP or for PMG excitation systems.Package Contents:1 x R448 Automatic Voltage Regulator1 x Instruction ManualNote:1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.2.Please allow slight manual measurement deviation for the data.Payment Payment must be completed within 5 days.
