Nobreak APC Smart-UPS 500VA Line-Interactive Rack 1U Short Depth (SC500RM1U)

500VA / 300W, Lead-Acid Battery, 1U Rackmount, 4x NEMA 5-15R Outlets, Stepped Sinewave, AVR, Compact Short Depth

The APC SC500RM1U provides reliable 500VA / 300W power protection in a compact 1U rackmount design. Built with line-interactive topology, Automatic Voltage Regulation (AVR), and stepped approximation to sine wave output, it safeguards entry-level servers, network devices, and storage from power fluctuations and outages. With a lightweight short-depth form factor, intuitive indicators, and a 3–5 year lead-acid battery design life, it is an efficient UPS solution for small IT environments and edge deployments.

• 500VA / 300W Capacity: Provides basic backup power for essential IT and networking devices.
• Compact 1U Rackmount: Short-depth design saves valuable rack space in dense IT environments.
• Automatic Voltage Regulation (AVR): Corrects voltage fluctuations without switching to battery, extending runtime availability.
• Stepped Approximation to Sine Wave: Reliable protection for non-sensitive loads and entry-level IT systems.
• Simple Status Indicators: LED display and audible alarms provide quick system status updates.
• ENERGY STAR® Certified: Energy-efficient design lowers operating costs.

The SC500RM1U is based on line-interactive UPS architecture with AVR to stabilize incoming voltage. By correcting over-voltage and under-voltage conditions before they impact equipment, the UPS extends battery life and ensures continuous uptime without frequent battery discharge.

Its sealed lead-acid battery (12V, 7Ah) provides dependable backup with a 3–5 year lifespan and a typical recharge time of 5 hours. The RBC replacement module ensures straightforward maintenance and consistent runtime availability. With a 500VA / 300W rating, it offers suitable backup for entry-level servers, POS systems, and small network devices.

The UPS delivers stepped sinewave output, which is effective for non-sensitive electronic loads and budget-conscious IT deployments. Integrated surge suppression (400 J) and full-time multi-pole noise filtering protect against spikes and electrical interference, enhancing system reliability.

• Entry-level rack-mounted servers and network devices
• Retail point-of-sale and small office IT systems
• Edge computing and branch office environments with limited rack space
• Storage, routers, and communication hardware requiring compact UPS protection
