features: 1,SX460 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator(AVR) and forms part of the exciation system for a brush-less generator.2,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 termainals.3,Positive voltage up from residual levels is ensured by the use of effcient semiconductors in the power circuitry of the AVR.4,Provision is made for the connection of a remote voltage trimmer,allowing the fine control of the generator output5,The AVR is linked with the main stator windings and the field windings to closed loop control of the output voltage with load regulation of +/-1.0%. In addition to being powered from the main stator, the AVR also derives a sample voltage from the output windings for voltage control purposes.Specifications:Color: blackMaterial: ABS+PCBModel: SX460Detection and power input: voltage 120 (95-132)/240 (190-264) V AC single-phase two-wire with jumper copper Field output: maximum 90V DC at 207V AC inputCurrent: continuous 4A, non-continuous 10A in 10 secondsVoltage regulation accuracy:Less than 1%System requirements: brushless generator within 80KWPackage Contents:1 x SX460 voltage regulatorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
