General Description / Specifications
SX440 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) and forms part of the excitation system for a brush-less generator.

In addition to regulating the generator voltage, the AVR circuitry includes under-speed and sensing loss protection features. Excitation power is derived directly from the generator terminals. Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR.The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.5%.

In addition to being powered from the main stator, the AVR also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.

A frequency measuring circuit continually monitors the generator output and provides output under-speed protection of the excitation system, by reducing the output voltage proportionally with speed below a pre-settable threshold. A manual adjustment is provided for factory setting of the under frequency roll off point, (UFRO).This can easily be changed to 50 or 60 Hz in the field by pushon link selection. Provision is made for the connection of a remote voltage trimmer, allowing the user fine control of the generator's output.

Product Details:

Introduction:For both AREP&PMG excitation systems,the alternator voltage regulator is the R438.With AREP excitation,the R438 electronic AVR is powered by two auxiliary winding which are independent of the voltage match circuit.The first winding has a voltage in proportion to that of the alternator,the second have a voltage in proportion to the stator current.The power supply voltage is rectified and filtered before being used by the AVR monitoring transistor.This consists of a "PMG"(permanent generator).This is fitted at the rear of the machinge and connected to the R438 AVR.The PMG supplies the AVR with constant voltage which is independent of the main alternator winding.As a result the machine has a short-circuit current capacity and good immunity to distrotions generated by the load.The AVR monitors and corrects the alternator output voltage by adjusting the exitation current.50/60Hz selection via the ST3 jumper.The LAM system is integrated in the R438 AVR as standard.Role of the "LAM(load adjustment module)"On application of a load,the rotation speed of the generator set decreases.When it passes below the preset frequenecy threshold,the LAM causes the voltage to drop by approximately 13% or 25% and consequently the amount of active load applied is reduced by approximately 25% to 50%,until the speed 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 the increase the applied load possible for one speed variation(turbo-charged engine).To lowest requency in steady state.During load impacts,the function help the genset to return to its rated speed faster thanks to a gradual increase in voltage according to the principle:If the speed drops between 46 and 50Hz,the rated voltage follows a fast gradient as it is restored.If the speed drops below 46Hz,since the engine need more help,the voltage follows a slow gradient as it returns to the reference value.
