APC SRTL3KRM1UNC 3000VA Online Rack/Tower UPS
Overview
The APC SRTL3KRM1UNC is a double-conversion online uninterruptible power supply engineered to deliver continuous conditioned power to critical IT systems. It is typically deployed by infrastructure engineers and data center technicians protecting servers, storage arrays, network core switches, and virtualization hosts that cannot tolerate voltage disturbances, frequency variation, or power interruptions. The online topology provides clean, regulated AC power at all times by converting incoming utility power to DC and then back to AC, eliminating transfer events during power anomalies.
This system provides 3000VA / 2700W output capacity with a pure sine wave output ideal for modern enterprise power supplies using active power factor correction. It is designed for 120V power environments and connects via a NEMA L5-30P input connector. The unit also features a mix of NEMA 5-20R and L5-30R output receptacles for downstream distribution to protected equipment.
The UPS supports both rack and tower installation, offering flexibility to deploy in standard 19-inch server or network racks as well as equipment room floors where rack space is limited. In rack configurations it occupies 3U of rack height, enabling integration with servers, storage, and network infrastructure requiring high-availability power protection. Optional external battery modules can be added to increase runtime for extended outage support.
Management and monitoring are provided through integrated network management capabilities and local display interfaces. The system supports Ethernet, USB, and serial communication for remote visibility, alerting, event logging, and automated system shutdown coordination with servers or virtualization management platforms.
A typical deployment includes a rack housing compute nodes, SAN storage, and aggregated networking infrastructure where continuous power conditioning and protection are required. In this scenario the UPS maintains stable output during prolonged outages and provides sufficient battery runtime to execute shutdown scripts or failover procedures.
This model is not intended for small desktop or workstation environments. Lower-capacity UPS systems are more appropriate for non-mission-critical applications or individual workstations.
