GAVR20A Voltage Regulator — sealed electronic voltage regulator for brushless generators What it does Stabilizes the output of brushless generators by automatically adjusting the generator’s excitation current. Designed as a sealed device for reliable operation in typical generator environments. Key benefits — why you need it Consistent, safer voltage: prevents over- and under-voltage events that can damage sensitive equipment. Fast, reliable response: extremely low start voltage and quick regulation minimizes fluctuations when loads change. Built for reliability: industrial-grade components and multiple independent protection circuits reduce failure risk and improve long-term stability. Performance and protection highlights Extremely low start voltage and fast response for stable voltage from engine start through changing load conditions. Temperature drift less than 0.05%/°C, maintaining accurate regulation across typical operating temperatures. Multiple independent circuit designs for enhanced safety and reliability. Low-frequency protection with controlled (slow) voltage rise to avoid sudden surges on generator start or during frequency shifts. EMI suppression circuitry to reduce interference with nearby electronics. High-capacity 8 A fuse for robust overload protection. Sealed construction to protect internal electronics from dust and moisture. Compatibility and configuration Model: GAVR20A Suitable for brushless generators rated for 220 VAC or 440 VAC. Programmable input allows use with generators configured for either 220 VAC or 440 VAC systems. Typical applications Home backup power: maintain steady voltage to refrigerators, freezers, and electronics during outages, protecting appliances from damaging voltage swings. Industrial or commercial generators: stabilize power for control panels, PLCs, and sensitive instrumentation where reliable voltage regulation matters. Portable and site generators: provide stable supply for power tools, lighting, and temporary equipment on construction or outdoor job sites. What to expect A compact, sealed regulator that fits into standard brushless generator excitation systems (installation specifics depend on your generator model). Improved voltage stability, faster response to load changes, and layered protections to reduce risk of equipment damage and generator downtime.
