A high PT usually means that there is serious liver damage or cirrhosis. Other things to know: Some patients take a drug called Coumadin (warfarin), which elevates the PT for the purpose of thinning the blood. This is not related to having liver disease because it is the Coumadin causing the PT to be high.
A battery backup, or uninterruptible power supply (UPS), is primarily used to provide a backup power source to important desktop computer hardware components.
A volt-ampere (VA) is the unit used for the apparent power in an electrical circuit, equal to the product of root-mean-square (RMS) voltage and RMS current. In direct current (DC) circuits, this product is equal to the real power (active power) in watts.ome devices, including uninterruptible power supplies (UPSs) , have ratings both for maximum volt-amperes and maximum watts. The VA rating is limited by the maximum permissible current, and the watt rating by the power-handling capacity of the device.
