A Standby UPS is a cost-effective solution for providing basic power protection for home offices and small businesses. It remains in standby mode under normal conditions, delivering power directly from the utility source to connected devices. When a power outage or voltage fluctuation occurs, the UPS instantly switches to battery power, ensuring uninterrupted operation for critical devices. Standby UPS units are typically compact and easy to use, offering protection for equipment like personal computers, routers, and small electronics from power surges, sags, and outages.
