Features:1. Stop fluctuation of voltage, automatically maintaining generator output terminal voltage at a set value.2. Prevent generator from suffering damages of voltage fluctuation or over load.3. Suitable for high levels of vibrations and harsh environments.4. Supply protected with an 8A fuse, slow action (supports10A for 10s).5. For the connection of a remote voltage trimmer, allowing the user control the generator's output finely.The R250 AVR is an analogic Automatic Voltage Regulator with transistor.Specification:Sensing/Power InputVoltage:120(90-140VAC) or 240(190-264VAC), 1 phase 2 wireMagnetic Field OutputVoltage:Max 100VDC at 120VAC inputCurrent:Continuous 8A, intermittent 10A within 10 secondsPressure Regulating AccuracyLess than +/-1%RMS with 4% engine governingProduct DescriptionColour: Blackmaterial: plasticPackage Contents:1 x Voltage RegulatorOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
