For $88.99, you’ll get a line-interactive 450W UPS suitable for running low or medium power desktop systems. It features automatic voltage regulation which maintains smooth, continuous operation of connected hardware during brownouts and overvoltages.
Pro Affordable automatic voltage regulation solution
In terms of hardware and electrical design, a line-interactive UPS (with automatic voltage regulation) is considerably more expensive than a simple standby UPS (without automatic voltage regulation). For around $88.89, a line-interactive UPS is quite a bargain. Line-interactive topology allows the unit to regulate voltage during surges or brownouts without switching to battery, effectively reducing the chance of premature battery failure.
