What does kVA mean? VA mean? 
The output of a UPS is measured in volt-amperes or VA (output voltage x output current). 
The term kVA refers to kilo-volt-amperes or VA x 1000.

What is the wattage and VA relationship? 
Put simply, real power (watts)/apparent power (VA) = power factor

What is the difference between on-line and off-line? 
On-line UPS implies that an electronic inverter is constantly supplying AC power to the load under all modes of operation. 
Off-line UPS supply input utility to the load during normal operation and revert to a battery-powered inverter during utility failures.

Is on-line UPS better? 
On-line UPS provide better overall power protection to the load than off-line. This protection includes power conditioning, 
regulated voltage and frequency, and zero translation time to battery during a utility failure.

How do I size a UPS for my application? 
Multiply the voltage rating of the equipment by the current rating of the equipment to obtain a VA rating. 
The UPS must be rated to deliver at least this VA rating. See the Partner Solutions section of our web site for more info.

Can a single UPS support more than one workstation or server? 
Yes, if the UPS is sized large enough for the application. Maintaining close proximity of the hardware to be supported is preferred 
to long distance electrical runs which can cause unwanted ground current imbalances. 
Our technical staff is available to assist in the design of the electrical distribution.

Can we change the voltage taps inside the UPS module to change the input voltage wiring? 
Taps inside the UPS module should only be changed by a qualified Gruber Industries Field Engineers.
