Brushless Generator Spare Parts AVR R450 Automatic Voltage Regulator Single or three phase voltage sensing with optional module



Product description:


Compatible Leroy somer R450 AVR is powered by two auxiliary windings which are independent of the voltage equal circuit.

The power supply voltage is rectified and filtered before being used by the AVR monitoring transistor. With PMG excitation, a perma-nent magnet generator (PMG) added to the alternator supplies the AVR with voltage. On Application of load, the rotation speed of the generator set deceases, when it passes below the preset frequency threshold the LAM causes the voltage to drop by approximately13% or 25% and consequently the quantity of active load applied is reduced by approximately 25% to 45%, until the spe-ed reaches its rated value again. Hence the LAM can be used either to reduce the speed variation (frequency) and its duration for a given applied load, or to increase the applied load probable for one speed variation (turbo-charged engine).
