What is a UPS System?
An Uninterruptible Power Supply (UPS) is a device that maintains power to PCs, servers, network equipment, audio/video equipment and computer peripherals during short power outages, and allows computer systems to safely shutdown during prolonged blackouts. UPS Systems also stop damaging power surges and filter disruptive line noise, while select models correct brownouts and over-voltages.
Why are UPS Systems necessary?
Power failures and network downtime cost businesses a lot of money, and data lost during those failures is often irretrievable. UPS Systems instantly respond to a power outage and can support equipment until a generator is up and running, or for prolonged periods with additional batteries.
How much power will your connected equipment require?
Make sure that the UPS can handle the total electrical load of the equipment that you want to connect to it. You can use our Load Calculator to determine your total load, and then choose a UPS with an Output Watt Capacity 20-25% higher than that total.
How much backup runtime do you need?
Runtime is the number of minutes that the UPS will be able to provide power from the battery when utility power fails. Runtime is important because it tells you how long your equipment will continue to run during a power outage before there's no more backup battery power.
Please note that adding more equipment to the UPS will result in a shorter runtime, while adding batteries will increase runtime.
What is the voltage of the equipment you're supporting?
In North America, the voltage used to power servers and networking equipment is typically 120V or 208/240V.
Europe and Asia typically provide 230V power.
Be sure that the UPS input plug matches the receptacles of your input power source.
Where do you plan to install the UPS System?
UPS Systems come in a variety of sizes and formats. The most common form factors are tower and rack-mount.
Tower models stand upright on the ground or on a desk/shelf, and are typically used in network workstations or desktop computer applications.
Rack-mount models can be mounted in standard 19" rack enclosures and can require anywhere from 1U to 12U (U=rack space). They are typically used in server and networking applications.
What type of UPS System do you need?
UPS Systems have varying levels of protection, from basic battery backup and surge protection to on-line operation and zero transfer time to battery. View the chart below to select the type that meets your needs.
Battery Backup Emergency backup power for utility power outages
Surge Protection Protection against power surges or spikes
Brownout Protection Maintains safe voltage levels without using battery power
Overvoltage Protection Keeps overvoltages from damaging connected equipment without using battery power
Pure Sine Wave Output Perfect power for sensitive electronics
Fully Online Operation Zero transfer time to battery
Small server racks, office networks
Mission-critical equipment in data centers and server rooms

How many receptacles should the UPS System have?
Make sure you have more outlets than the number you need to ensure room for future growth. Most rack-mount UPS applications will require a Power Distribution Unit (PDU) to accommodate extra equipment plugs.
Do you need any special features?
Select UPS Systems accept external battery packs that extend runtime during a blackout.
Do you need uptime even during maintenance? Hot-Swap UPS Systems have a detachable PDU with a manual bypass switch that enables live UPS repair or replacement.
Remote Power Management
The SNMPWEBCARD network management accessory turns any expansion slot-equipped UPS into a managed device on the network. Remotely monitor energy usage and reboot unresponsive equipment from anywhere.
UPS Systems have varying levels of protection, from basic battery backup and surge protection to Automatic Voltage Regulation (AVR) and pure sine wave output. View the chart below to select the type that meets your needs.
