Voltage Regulation (power conditioning)

This is a measurement of a voltage stabilizers
ability to hold its output close to the nominal
rating despite a fluctuating input. This is
normally expressed as a +/- percentage.

Voltage Regulation

The voltage drop that will occur in the
transformer under full load as a percentage of
the open circuit voltage rating of the winding.
Varies with load and power-factor of the load-
.1% to 10% might be outside limits of normal
range.
