Features:SX460 is a half-wave phase-controlled thyristor type automatic voltage (AVR) and forms part of the excitation system for a bruch-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 builds up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR. Runs freely in high-temperature environment, responds extremely fast, builds voltage quickly, stable and reliable, giving you a fine quality experience.Specifications:Main material: PCBMain color: blackInput power: 7,8=100V~265V AC 50/60HzMaximum output:6A, 63V DC (when the input power is 220V AC)6A, 40V DC (when the input power is 110V AC)Voltage regulation factor: 1%Generator field resistance: 12 (minimum)External potentiometer: 2K1/2W potentiometer 8%Voltage establishment (initial): when the residual magnetic voltage is greater than 5V/25Hz, the voltage is automatically established.Build voltage time: 1.8sOperating temperature: -40C~60CRecovery time: 2sItem size: 136 * 102 * 38mm / 5.4 * 4.0 * 1.5inItem weight: 360g / 12.7ouncePackage size: 175 * 150 * 65mm / 6.9 * 5.9 * 2.6inPackage weight: 400g / 0.9lbPackage list:1 * Automatic Voltage Regulator AVR SX460
