VAR is an abbreviation of "Value-Added Reseller".

A VAR is a company that adds some feature to an existing product, then sells it (usually to end-users) as a new package. This practice is common in the electronics industry, where, for example, a software application might be added to existing hardware.

Cf. OEM (original equipment manufacturer)

VAR (or var or VAr) is also an abbreviation of volt-ampere reactive, a unit which is the imaginary counterpart of the watt. The relationship between VARs and watts in an alternating-current electrical system is determined by the power factor.
