The SX440 AVR Generator Voltage Regulator is a half phase-controlled thyristor type device, forming an integral part of the excitation system for your brushless generator. Ensuring smooth generator operation even in harsh conditions, the AVR is sturdy and reliable. Utilizing surface mount technology (SMT), our Automatic Voltage Regulator presents a high integration within a compact AVR. This remarkable alignment not only ensures efficient functionality but also guarantees a long lifespan and less maintenance. The AVR ensures positive voltage build up from levels due to the use of proficient semiconductors in its power circuitry. This feature enhances the power output of your generators, providing you with efficient and uninterrupted energy supply. The AVR circuitry is not just designed for regulating the generator voltage but also includes under speed and sensing loss protection. This feature provides an added layer of protection, ensuring safe and reliable control of your generator under all circumstances. Our AVR features separate terminals for control and voltage sensing circuits. This empowers you with the flexibility to derive excitation power directly from the stator winding for necessary applications or from an auxiliary winding if sustained short circuit performance is essential.
