A power conditioner (also known as a line conditioner or power line conditioner) is a device intended
to improve the quality of the power that is delivered to electrical load equipment.
While there is no official definition of a power conditioner, the term most often refers to a device
that acts in one or more ways to deliver a voltage of the proper level and characteristics to enable
load equipment to function properly.
In some usages, power conditioner refers to a voltage regulator with
at least one other function to improve power quality (e.g. noise suppression, transient impulse protection, etc.).
