Feature:1. An electronic device that allows the alternator to produce a fixed output voltage2. Has an open chassis, resin molded design, and is designed to be installed in the junction box of an alternator3. The device measures the voltage between one of the phases of the alternator and the neutral point, and adjusts the DC voltage applied to the field winding until it reaches the required alternator voltage4. Output stage of the device is a half-wave thyristor output related to the freewheeling diode5. Basically, the device is compatible with all brushless alternators, and for this purpose a stability adjustment potentiometer is also provided6. AVR includes a low frequency protection circuit. This function can reduce the output voltage during overload or engine stopSpecification:Item Type: Voltage Regulator GeneratorNumber of Phases: Single PhaseVoltage Adjustment Range: 210-250V MinimumFrequency: 50/60HzFrequency Protection Adjustment Range: 40-50HzOutput Voltage: 0-115VDC (230V)Output Current: 10A Continuous, 20A (Forced for 5 Seconds)Supply Voltage for Construction: 5 Volts MinimumAdjustment: Typically 2%Power Output Stage: Half-Wave ThyristorOperating Temperature: -10 (14) to 60 (140)Storage Temperature: -20 (-4) to 80 (176)Maximum Humidity: 95% Non-CondensingLength: Approx. 125mm / 4.9inWidth: Approx. 68mm / 2.6inHeight: Approx. 35mm / 1.3inFixed Center: Approx. 115mm / 4.5in, 2xM6.Package List:1 x Voltage Regulator4 x Wire1 x User ManualNote:Installation, connection, and inspection must be carried out by personnel with professional knowledge.
