APC SRTL2K2RM1UC 2200VA Online Rackmount UPS
Overview
The APC SRTL2K2RM1UC is a compact double-conversion online uninterruptible power supply designed for rack-based IT environments that require continuous power conditioning and battery backup. Infrastructure teams deploy this UPS to protect critical systems such as edge servers, network switches, and storage nodes from utility outages, voltage fluctuations, and frequency instability. Its online topology isolates connected equipment from upstream electrical disturbances by continuously regenerating clean AC power.
This unit delivers 2200VA / 1950W output capacity at 120V with a pure sine-wave output suitable for modern IT equipment using active power-factor-corrected power supplies. The UPS integrates lithium-ion battery technology, enabling longer battery service life and reduced maintenance compared with traditional sealed lead-acid systems. Standard connectivity includes a NEMA 5-20P input plug and a mix of NEMA 5-20R and L5-20R output receptacles for rack-level power distribution.
The system fits into a 1U rack footprint, enabling deployment in shallow or space-constrained racks commonly found in branch offices, telecom cabinets, and edge computing environments. Because of the compact chassis and mounting flexibility, the unit can be installed in traditional 4-post racks, 2-post network racks, or alternative mounting orientations such as tower or wall installations.
Management and monitoring are supported through Ethernet, USB, and serial interfaces. The platform integrates with centralized power management systems and cloud-based monitoring tools, enabling remote visibility, alerting, and coordinated shutdown of connected systems during extended outages. This capability is important for distributed IT deployments where infrastructure may be installed in remote locations or unattended facilities.
A common deployment example includes an edge compute rack supporting a virtualization host, firewall appliance, and aggregation switch. The UPS maintains conditioned output power and provides several minutes of runtime during outages, allowing automation tools to migrate workloads or perform controlled system shutdowns.
This model is not intended for high-density server racks requiring several kilowatts of runtime capacity or for facility-level UPS installations protecting entire data halls. Those environments typically require larger modular UPS systems or higher-capacity rackmount platforms with external battery cabinets.
