Function and protection Builtin suppression circuit with low frequency protection provides a smooth voltage ramp to reduce surges and help stabilise the generator output. Size and construction Small, compact and robust design suitable for tight spaces and regular use. Compatibility and voltage control Suitable for generators; allows easy adjustment of output voltage to stabilise the generator output. Performance and reliability Improves voltage stability, reduces fluctuations, and protects connected equipment for more reliable generator performance. Use scenarios Home backup: use with a household generator to keep lights and essential appliances operating smoothly during power outages. Construction site: pair with a portable generator to protect power tools and sensitive electronics from voltage swings. Recreational/workshop use: connect to a small generator at camp or in a workshop to maintain consistent voltage for electronics and tools.
