Ensure stable and reliable generator performance with this 4-pack of universal brushless automatic voltage regulator modules. Designed for 220/400VAC systems, each module delivers precise voltage control with less than ±0.5% regulation, protecting sensitive equipment from power fluctuations. The rugged metal and PC construction withstands demanding environments. Key features include soft-start voltage ramping for gentle 3-second startup, under-frequency protection, and a 15A high-capacity fuse for added safety. An external trimmer allows ±7% voltage fine-tuning to match your specific needs. Easy to install and compatible with a wide range of generators.
