APC Smart-UPS, Line Interactive, 500VA, Lithium-ion, Rackmount 1U, 120V, 4x NEMA 5-15R outlets, Network Card, Short Depth

Overview

The APC SCL500RM1UNC is a line interactive uninterruptible power supply (UPS) designed to protect small servers, network switches, and other critical devices from power interruptions. Delivering 500 volt-amps of pure sine wave output, it ensures stable and clean power to sensitive electronics. Its lithium-ion battery offers a longer service life compared to traditional lead-acid batteries, reducing maintenance and downtime. The compact 1U rackmount design with short depth fits easily into shallow racks and tight IT spaces.

Key features

• Pure sine wave output that safeguards connected equipment from surges, sags, and outages
• Lithium-ion battery technology providing an estimated eight to ten years of service life, cutting replacement frequency
• Space-saving 1U rackmount form factor with short depth ideal for wall-mount racks and crowded network closets
• Four NEMA 5-15R outlets with two outlets grouped for remote switching to extend battery runtime for essential devices
• Preinstalled network management card enabling remote monitoring, event logging, and safe shutdown via PowerChute software or web browser
• Automatic Voltage Regulation (AVR) that stabilizes output voltage without using battery power
• Fast transfer time of six milliseconds to bridge brief power interruptions seamlessly
• Designed to operate reliably in ambient temperatures up to 104 degrees Fahrenheit, suitable for warmer or less ventilated environments
• Includes PowerChute software for controlled system shutdown to prevent data loss
• Five-year warranty covering both the UPS unit and lithium-ion battery for long-term peace of mind

Connectivity and compatibility

The UPS includes a factory-installed network management card that integrates with your existing monitoring platforms. This allows IT administrators to track battery health, monitor power events, and initiate safe shutdowns remotely. The four NEMA 5-15R outlets provide standard 120 V power connections for a variety of small IT equipment. Two of these outlets can be switched off remotely to conserve battery power for critical devices during extended outages.

Ideal uses and environments

This UPS is well suited for branch offices, retail point-of-sale systems, edge computing closets, and home labs where space is limited and ambient temperatures can be higher than typical data center conditions. Its compact size and short depth make it a strong choice for shallow racks and wall-mounted enclosures. The lithium-ion battery’s long lifespan and the unit’s robust design help reduce maintenance efforts and ensure continuous protection for essential electronics in demanding environments.
