Stable and reliable operation This AVR voltage regulator is built with quality electronic components to deliver stable, dependable performance for generator voltage regulation. Wiring harness and connections The wiring harness consists of 6 wires (4wire socket plus 2 carbon brush wires). The red wire is the positive connection. This configuration supports straightforward integration with compatible AVRequipped generators. Singlephase compatibility and mounting Designed for singlephase generator systems. The installation hole distance is 140 ± 1 mm, allowing for secure mounting in standard AVR applications. Protections and safety Equipped with overvoltage, overcurrent, and shortcircuit protections to safeguard the generator and connected electrical equipment. Key attributes Function: AVR voltage regulation to stabilize generator output Compatibility: suitable for singlephase generators with appropriate mounting Size and mounting: installation hole distance 140 ± 1 mm Wiring: 6wire harness (4wire socket + 2 carbon brush wires); red is positive Performance: designed for stable voltage regulation with protective features Use scenarios Home backup power: stabilize voltage from a residential generator during outages to protect appliances. Construction sites: provide steady voltage to power tools and equipment from a portable generator. Remote or agricultural operations: maintain consistent voltage for sensitive equipment on singlephase gensets.
