Maintain power continuity for essential rack-mounted equipment with a UPS designed for tight spaces and modest load requirements. The APC Smart-UPS SC 500VA 120V combines a 1U rack form factor with line-interactive protection, giving you a compact layer of defense for switches, routers, and other critical edge devices. This model is built for environments where rack space is limited and uptime still matters. Its 500 VA / 300 W capacity is well suited to lower-density deployments that need orderly shutdown support and short-duration backup power during utility disturbances. The 120 V input and output profile aligns with common North American rack power environments, while the rackmount design keeps the installation clean and predictable. For procurement teams, the value is in fit and function: enough capacity for essential loads, without paying for runtime or management features you may not need. For infrastructure teams, it offers a straightforward way to protect small rack segments, branch office gear, and network edge hardware with a trusted APC platform.
