CyberPower OR500LCDRM1U Smart UPS
The OR500LCDRM1U provides 500VA / 300W with a simulated sine wave output and six NEMA 5-15R outlets. Four are battery-backed and surge-protected, while two are surge-protected only. It features a multifunction LCD panel showing runtime, battery status, and power conditions, helping IT staff anticipate issues before downtime occurs. Ideal for small office servers, network devices, and telecom gear that do not require Active PFC compatibility.
Best for: small workgroups or network closets needing visible runtime information and reliable surge protection. This model is a strong pick when remote management is optional via an additional card.
Caution: The LCD can help monitor status, but this unit does not include built-in remote management without the management card.
CyberPower OR700LCDRM1U Smart UPS
The OR700LCDRM1U delivers 700VA / 400W with six outlets and a 1U rack footprint. It uses a simulated sine wave output suitable for equipment without Active PFC power supplies and includes a multifunction LCD panel for runtime and status. It’s a better option for slightly larger network gear or smaller servers that require more headroom than the 500VA unit.
Best for: growing small offices or labs with additional devices that still need compact, rack-mount power protection. The higher wattage reduces the risk of overload during outages.
Caution: Remote management remains optional via a separate card, so plan ahead if you need centralized monitoring.
CyberPower CP500PFCRM1U PFC Sinewave UPS
The CP500PFCRM1U offers 500VA / 300W with a sinewave output designed to support Active PFC and conventional power supplies. It provides four battery-backed outlets and two surge-protected outlets among the six total, plus a 10-foot cord. A multifunction LCD panel shows runtime and status, with optional remote management through a card. This model is a strong choice for sensitive AV, networking, and security systems that require clean power.
Best for: setups with Active PFC equipment that need true sinewave output to maintain device integrity during outages. It’s a good fit when you want reliable surge protection alongside battery backup.
Caution: Like other basic 1U units, remote management requires an extra card, so plan for that if you need centralized control.
CyberPower OR1500LCDRM1U Smart UPS
The OR1500LCDRM1U provides a substantial 1500VA / 900W capacity with six outlets. It uses a simulated sine wave and includes an LCD panel for runtime and status updates. It is well-suited for mid-range servers, routers, and telecom devices that require more headroom while remaining in a 1U footprint. Remote management is available via the optional RMCARD205.
Best for: networks or small data closets needing higher backup capacity without stepping up to a larger, bulkier unit. It gives more reserve capacity for sudden outages or longer outages.
Caution: Larger capacity means a slightly higher initial cost and potential rack-space planning considerations in tight environments.
Tripp Lite SMART500RT1U
The SMART500RT1U is a 500VA line-interactive UPS with 1U rack/tower form. It includes six NEMA 5-15R outlets, including one that can be individually controlled for load shedding. It supports USB and RS232, plus optional SNMP/Web cards for monitoring. It’s a practical choice for networks requiring integrated remote management and basic watchdog capabilities for remote reboot options.
Best for: small offices seeking a cost-effective, line-interactive solution with basic remote options and load-shedding control. It’s a straightforward upgrade from older, non-smart units.
Caution: Some users may prefer sinewave output for highly sensitive electronics; verify device compatibility if you have high-sensitivity equipment.
Buying Guide
- Power capacity vs. load: Match the UPS VA rating to your critical devices’ total load. A higher VA rating provides longer runtime and more headroom during outages.
- Output waveform: Sinewave or simulated sinewave is better for Active PFC devices and sensitive electronics. Choose sinewave for high-end servers and AV gear.
- Outlet configuration: Ensure there are enough battery-backed outlets for essential devices and enough surge-only outlets for non-critical gear.
- Remote management: If centralized monitoring is needed, look for models with optional management cards or built-in network interfaces.
- LCD vs. status alarms: LCD readouts help operators monitor runtime and conditions in real time, reducing downtime risk.
- Physical footprint: All options here fit in a 1U rack; confirm rack depth and mounting clearance in your cabinet.
- Protection features: Beyond battery backup, consider protection like AVR (voltage regulation) to guard against sags and surges.
FAQ
- What is 1U rackmount UPS used for? It provides backup power for network gear, small servers, and telecom devices in a compact, rack-mountable form factor.
- Should I choose sinewave or simulated sinewave UPS? Sinewave is preferable for devices with Active PFC power supplies or sensitive electronics; simulated sinewave works for general use with compatible gear.
- Do these UPS units offer remote monitoring? Some models require an optional management card to enable remote monitoring and control.
- Which 1U UPS has the most outlets? The models listed provide six outlets total, with a mix of battery-backed and surge-protected configurations.
- Is a higher VA rating always better? Not always; choose a rating that covers your total load with some headroom for growth and longer outages.
- Can I use these in a cold data center? Yes, but consult manufacturer temperature specifications to ensure reliability in your environment.
