Voltage Stabilizer units are used primarily for two
applications, Mains Conditioning and Process Control
Mains Conditioning
In situations where the mains supply voltage fluctuates
beyond the normal tolerance limits, problems can arise
with the reliability, operational function and life
expectancy of equipment.
Steadyvolt Servo Stabilizers are designed to overcome
this problem by providing a stable supply for trouble
free operation of electrical equipment.
Process Control
Steadyvolt units can also be used to provide stable
voltages where the normal fluctuations in mains tolerance
are not considered operationally acceptable, such as
for long term testing of electrical goods at specific
voltages.
They can also be used for regulating operational processes
such as the accurate speed of a pump or the temperature
of a heating element.
The Steadyvolt units consists of either a motorised
variac used directly, or in combination with an isolation
transformer in a Buck-Boost configuration. The output
of the unit is controlled automatically with a feedback
sensing circuit that operates the motor drive unit on
the variac to prevent over voltage or under voltage
situations.
