Selecting the right UPS (Uninterruptible Power Supply) for your needs requires understanding a few key specifications. First, determine the VA (Volt-Ampere) rating needed by calculating the total power draw of equipment you need to protect. For home office setups, a 1000-2000VA unit typically suffices, while business servers may require 3000VA or higher. Powershield options range from 2000VA to 10kVA to match various requirements.
Consider the UPS topology that suits your environment. Line-interactive UPS systems provide basic protection for workstations and are more affordable, while double conversion online UPS systems (like the Powershield Centurion series) offer premium protection for servers and critical equipment by continuously converting power and providing perfect sine wave output. Form factor matters too—tower units save rack space, while rack/tower convertible models like the Centurion RT series offer installation flexibility.
Additional features to consider include runtime (how long the UPS can power your equipment during an outage), management capabilities (such as Ubiquiti's managed UPS with network monitoring), and expandability. For environments requiring extended runtime, models like the Powershield Centurion RT Long Run series allow for additional external battery modules. Remember that proper sizing is crucial—an undersized UPS won't adequately protect your equipment, while an oversized one represents unnecessary expense.
Calculate your total power requirements in watts or VA (typically listed on equipment). For safety, choose a UPS rated 20-25% higher than your total load. Most home/small office setups need 1000-3000VA, while servers may require 6000VA or higher.
Line-interactive UPS systems provide basic protection with battery backup during outages and some voltage regulation. Online double conversion UPS continuously converts AC to DC and back, providing complete isolation from power problems—ideal for servers and critical equipment.
Yes, we stock rack-mountable UPS systems like the Powershield Centurion RT series in various capacities. These rack/tower convertible units can be installed in standard 19" racks with optional rail kits available for purchase.
Runtime depends on the UPS capacity and connected load. Typical UPS systems provide 5-15 minutes at full load—enough to safely shut down equipment or bridge brief outages. For extended runtime, consider models with external battery expansion options.
