CyberPower CP1500PFCRM2U PFC Sinewave UPS
The CyberPower CP1500PFCRM2U offers a compact 2U rack footprint with eight NEMA 5-15R outlets and a 1500VA/1000W capacity designed to support active PFC and conventional power supplies. It features a right-angle NEMA 5-15P input, a six-foot power cord, and a multifunction color LCD panel that provides real-time battery and power condition information. This model is well-suited for safeguarding security systems, AV equipment, and networking devices in mid-range rack deployments, with audible and visual alerts to help prevent downtime.
CyberPower CP2000PFCRM2U PFC Sinewave UPS
The CP2000PFCRM2U delivers 2000VA/1200W with eight NEMA 5-20R outlets and a six-foot input cord. Its PFC sinewave output remains stable for active PFC and conventional supplies, making it suitable for larger rack environments and networked equipment. The color LCD panel communicates runtime, battery status, and power conditions, while the AVR functionality helps mitigate brownouts and overvoltages to protect critical hardware from downtime.
APC 1500VA Smart UPS with SmartConnect
The APC SMC1500-2UC Rack Mount UPS provides 1500VA / 900W of pure sine-wave power with AVR to adjust voltage fluctuations and preserve battery life. It includes six NEMA 5-15R outlets (six total) and a straightforward NEMA 5-15P input. SmartConnect support enables remote monitoring and management when paired with compatible APC services, giving IT teams visibility into battery health and load. This unit is ideal for servers, networking gear, and workstations in compact rack spaces.
Tripp Lite SMART1500LCD 1500VA Rack Mount UPS
The SMART1500LCD provides 1500VA / 900W with eight outlets and AVR to correct brownouts. A six-foot input cord makes connection to AC outlets simple in most rack setups. The onboard LCD screen displays run-time estimates, battery status, and power conditions. The unit follows PWM sine-wave operation in battery mode and true sine-wave output in AC mode, suitable for varied loads, including servers and workstations. It supports remote management via optional RMCARD205 module for centralized control.
Tripp Lite SMART1500LCDXL 1500VA Rack Mount UPS
The SMART1500LCDXL extends runtime options with an expandable runtime capability and an external battery pack path. Offering 1500VA / 900W, it includes eight NEMA 5-15R outlets and a 2U footprint that can mount in racks or stand as a tower. AVR helps stabilize voltage, ensuring devices remain protected during grid fluctuations. The LCD provides essential readouts, and the model supports remote management through optional RMCARD205, enabling centralized control for multiple UPS devices in professional environments.
Buying Guide: Key Considerations For Rack-Mount UPS Purchases
Power capacity and efficiency: Choose a UPS with enough capacity (VA/W) to cover the critical devices and a buffer to handle startup surges. Look for models with pure sine wave or high-quality simulated sine wave outputs that suit active PFC power supplies.
Form factor and rack compatibility: Most options here are 2U rack-mountable, with some offering a tower or 2U expansion. Verify the equipment rack depth and mounting rails compatibility to ensure a proper fit in your setup.
Outlets and connection configuration: Count the number and type of outlets (NEMA 5-15R vs 5-20R) and ensure they match the devices you plan to protect. Consider whether you need battery-backed outlets for critical equipment and separate surge-only outlets.
Voltage regulation and runtime: Automatic Voltage Regulation (AVR) helps neutralize brownouts and overvoltages without draining the battery. Evaluate the expected runtime at your typical load and whether you may need an extended-runtime option with an external battery pack for longer outages.
Management and monitoring: Remote management capabilities, such as LCD panels, network management cards, or cloud-based monitoring, provide visibility into battery health, runtime estimates, and alarms. This is especially valuable in data centers or distributed IT environments.
Ease of service and warranty: Consider models with accessible battery replacements, warranty terms, and vendor support. A unit with a familiar interface and straightforward remote management tends to reduce maintenance effort over time.
Compatibility with your devices: If you rely on active PFC power supplies or sensitive AV components, prioritize UPS units that deliver clean sine-wave output in battery mode, and ensure the UPS firmware and management options align with your IT stack.
Expandability: Some models support external battery packs that extend runtime significantly. If you anticipate longer outages or future equipment growth, choose a system that allows modular runtime expansion.
