APC Smart-UPS SC420I 420 VA 230 V RS-232 | Desktop UPS, Entry

Maintain power continuity for essential single-device deployments with the APC Smart-UPS SC420I. Rated at 420 VA and 260 W, it is sized for modest loads where clean shutdown and basic protection matter more than extended runtime. The 230 V input and output profile makes it suitable for standard international desktop environments, while the DB-9 RS-232 interface supports direct management in legacy-friendly setups. This model fits well where space is limited and the power requirement is focused: a workstation, a small network appliance, or a point-of-use device that cannot afford abrupt loss of power. Its compact desktop form factor keeps installation simple, and the Smart-UPS line gives procurement teams a familiar platform for dependable backup power without overbuying capacity. For organizations that need a practical UPS rather than excess wattage, the SC420I offers a clear fit. It provides the essential layer between utility power and sensitive equipment, helping reduce downtime risk and protect work in progress when outages or brief disturbances occur.
