True sine wave and line-interactive voltage regulation
True sine-wave output
True sine-wave output provides assurance of compatibility with all loads.
Line interactive
Innovative line-interactive design uses the DC to AC power inverter “in reverse.” It acts like a battery charger,
providing greater performance and efficiency during normal operation.
By cleaning and conditioning utility power with line-interactive voltage regulation, this UPS creates true,
sine-wave output to provide safe and continuous power. Additionally, the unit features easy installation and
implementation as well as rapid recharging via independent battery charges.
High-line (208V) versus low-line (120V)—
What’s best for your customer
Choosing between voltages is mainly a North American* issue. What might be confusing is that some
individuals make references to 120V power, others mention 110V power or even 117V power. These disparate
figures are essentially the same. Additionally, 120V is sometimes described as low voltage. Low voltage in
correct electrical specifications is a range from 100V-120V. Most homes and office spaces in North America are
wired for 120V. For marketing purposes, Belkin chooses to use low voltage to mean 120V.
The other choices for North American single-phase voltage environments are generally 208V and 240V. These
voltages are sometimes described as high voltage. High voltage in correct electrical specifications is a range
from 200V–250V. For marketing purposes, Belkin chooses to use high voltage to mean 208V.
For commercial buildings, 208V refers to the high-line power available. For residential and some
heavy-industrial buildings, high-line power is 240V. A typical example of residential high-line power is the
household dryer that runs off of 240V.
Most servers have an auto-sensing feature that allows the server to automatically adjust to voltage levels
ranging from 100V–240V. Therefore, they can be powered off of any of these voltages.
How much power is needed?
How much power does the equipment require, and how much power is available in the existing computer
room? Assume that within the computer room there is a single power outlet rated at 120V and 15 Amps. This
configuration is a standard and typical wall outlet, which is also found in most residential homes. The amount
of power available would be calculated by taking 120V and multiplying it by 15 Amps, giving a preliminary
available power figure of 1,800VA. A quick yet important safety note here: It is a safety regulation that you
use only 80% of your available power in order to keep breakers from tripping and outlets from overloading.
Keeping this safety regulation in mind reduces the safe available power to 1,440VA.
