Servo
Controlled Voltage Stabilizer
This
is a stabilizer, which constantly monitors the output voltage
and controls the variations in the input voltage
by
movements of a motor. This motor in turn selects the proper
output voltage on the variable transformer
(variac).
This
is probably the cheapest power-conditioning product available.
It gives reasonably good voltage regulation and is all
right where voltage fluctuations are not considerable.
However
it is not advisable to use it outside big cities where apart
from considerable fluctuations in voltage, the power is full
of frequency drifts, failures, noise and spikes.
