CyberPower OR2200PFCRT2U PFC Sinewave UPS

The OR2200PFCRT2U combines 2000VA/1540W with a PFC sinewave output and eight battery-backed outlets (two 5-20R and six 5-15R). It uses a NEMA 5-20P right-angle input with a ten-foot cord. A rotatable multifunction LCD panel displays key battery and power metrics, including runtime estimates and load data. This model is well-suited for small servers, network devices, and telecom gear in 2U rack or tower configurations, offering flexible mounting options and robust protection against voltage fluctuations and power loss.
APC SMT2200RM2UC Rack-Mount UPS

The APC 2200VA SMT2200RM2UC provides a pure sine wave output with automatic voltage regulation, suitable for a wide range of IT equipment. With 1980W of output power and a rack-mountable 2U form factor, it supports critical servers, switches, and workstations while offering robust surge protection across six 5-15R outlets and two 5-20R outlets. The unit is designed for line-interactive operation and clean power delivery, helping extend battery life and preserve equipment during power disturbances. This model is a solid choice for mid-to-large rack deployments where reliability matters.
Buying Guide: Key Purchase Considerations For Rack-Mount UPS Backups
Power capacity and runtime: Match VA/W ratings to your equipment’s surge and runtime needs. Online double-conversion UPSes offer the most seamless protection for sensitive devices, while line-interactive models can be more cost-efficient for mixed loads. Consider future expansion when choosing wattage.
Outlets and configuration: Ensure enough outlets for all devices and check the mix of NEMA 5-15R and NEMA 5-20R outlets. Verify whether the unit supports both battery backup and surge protection on specific outlets, and whether you need six, eight, or more outlets for your rack layout.
Rack compatibility and footprint: A true 2U rack-mount design simplifies installation in standard server racks. Short-depth variants save space in compact enclosures, but confirm clearance behind the rack for heat dissipation and cable management.
Voltage regulation and waveform: Automatic Voltage Regulation (AVR) helps maintain safe output during brownouts and overvoltages, preserving battery life. Sine-wave or pure sine-wave output is important for servers and network gear, reducing distortion and protecting sensitive components.
Management features: LCD or color display panels provide real-time run-time, load, and health information. Remote management options, battery modules for longer runtimes, and optional management cards can offer granular control and monitoring in data-center environments.
Durability and certification: UL-certified units meet safety and performance standards. For critical operations, prioritize units offering robust surge protection, EMI/RFI filtering, and long-term reliability under continuous load.
Expandability and replacement parts: If you anticipate growth, select UPS models with expandable battery modules or widely available replacement batteries. Compatibility with add-on monitoring cards and network management tools is a plus for enterprise setups.
