System Compatibility: Pure sine wave provides 300W of quality AC equivalent to grid power
More Power Available: 600W peak/surge power. Toroidal transformer design generates clean wave form throughout the range of input voltages. High efficiency and low self consumption maximizes available load power. Automatic stand-by reduces consumption during no load conditions
Extensive Protection and Diagnostics Built-In: Automatically protects against faults and user mistakes such as short circuit, overload, high temperature and low voltage disconnect. Recovery from most faults is automatic
Lowest Hardware Failure Rate In The Industry, Backed By A Two-Year Warranty: Most Morningstar products ever built are still in use, some for over 25 years, thanks to smarter digital design, superior internal engineering, and over-spec components. Advanced thermal engineering eliminates cooling fans which can fail, suck in dirt, shorten component life and waste precious energy. The high-impact, durable polycarbonate exterior case illustrates industrial-strength build quality.
