APC 1500VA Smart UPS with SmartConnect

The APC SMC1500-2UC (SmartConnect) provides 1500VA / 900W of power with a pure sine wave output, suitable for servers and professional workstations. It features Automatic Voltage Regulation (AVR) to stabilize fluctuating mains without drawing battery power, and six NEMA 5-15R outlets for critical devices. The unit is designed for clean power delivery in 2U rack spaces, with a focus on reliability and manageability for network gear, desktops, and hybrid work environments.
Key benefits include protecting sensitive electronics from brownouts and surges while maintaining uptime during outages. The AVR capability helps extend battery life by reducing unnecessary cycles, making it a solid choice for small data rooms and IT closets requiring dependable power without frequent battery drain.
Tripp Lite SMART1500LCD 1500VA Rack Mount UPS

The Tripp Lite SMART1500LCD combines 1500VA / 900W capacity with eight NEMA 5-15R outlets, providing robust battery backup and surge protection for servers, PCs, and peripherals. It includes a six-foot input cord and offers 2U rack mounting or vertical tower operation with an included adapter. The unit uses AVR to correct brownouts and overvoltages, returning to 120V without draining the battery power. In battery mode, it delivers a Modified Sine Wave output, while AC mode supplies a Sine Wave signal for low total harmonic distortion, supporting a wide range of equipment.
This model is well-suited for small server rooms, home labs, or network closets where multiple devices require reliable protection and straightforward setup. It provides practical runtime management and easy integration with existing rack infrastructure.
CyberPower OR1500LCDRTXL2U Smart App LCD UPS

The CyberPower OR1500LCDRTXL2U delivers 1500VA / 1125W with 8 NEMA 5-15R outlets and AVR in a 2U rack/tower form factor. The Smart App LCD interface provides runtime estimates, battery status, and power condition alerts. It supports remote management via an optional management card, making it suitable for IT networks and department-level servers. The unit uses a simulated sine wave output, suitable for most Active PFC and traditional power supplies, with a right-sized power cord for convenient installation in standard racks.
Its expandable runtime option and remote management capability help IT teams scale protection as requirements grow, while maintaining straightforward operation and monitoring across a networked environment.
CyberPower OR700LCDRM1U Smart App LCD UPS

The CyberPower OR700LCDRM1U is a compact 1U rackmount UPS delivering 700VA / 400W with AVR and a six-outlet configuration. It uses a simulated sine wave output and includes a multifunction LCD panel that shows runtime, battery status, and power conditions. The unit supports remote management through an optional card, enabling network administrators to monitor and respond to power events. This option is ideal for small server rooms or network closets where space is at a premium but reliable backup power is essential.
With a 10-foot power cord and a straightforward setup, it provides essential protection for switches, routers, and small servers while reducing downtime risk during outages or power irregularities.
CyberPower OR2200PFCRT2U PFC Sinewave UPS

The CyberPower OR2200PFCRT2U offers 2000VA / 1540W with eight outlets, including six battery-backed and two surge-protected, designed for Active PFC or traditional power supplies. It features a rotatable Multifunction LCD panel showing runtime estimates, load, and battery status, plus remote management via an optional card. The 2U rack/tower form factor provides flexibility for growing IT environments and can support more demanding equipment like small servers, access controllers, or virtualization workstations. The PFC sinewave output helps maintain compatibility with modern, energy-efficient devices while delivering clean power under load.
Buying Guide
- Power capacity and outlets: Match VA/W ratings and the number of outlets to your equipment count and power draw. Higher-end models often offer more battery-backed outlets and automatic voltage regulation for sensitive equipment.
- Output waveform: For Active PFC PSUs and sensitive electronics, sinewave or PFC-compatible sinewave outputs provide cleaner power and better performance than basic simulated sinewave.
- Form factor and mounting: Verify 1U/2U compatibility and whether a unit supports rack mounting or tower installation, depending on your space and cabling layout.
- Management and monitoring: Look for LCD readouts, runtime estimates, and optional remote management cards or software. This helps anticipate downtime and plan maintenance or load shedding.
- Expandable runtimes: Some UPS models support external battery packs to extend runtime, which can be crucial for longer outages or data center-like setups.
- Safeguards and features: AVR to correct voltage fluctuations, surge protection, and battery protection features are important for preserving equipment longevity and avoiding unnecessary battery drain.
- Compatibility and certification: Ensure UL-certified models meet safety standards and compatibility with your existing devices and network infrastructure.
