Product Details

Variacs or variable auto transformer is a Continuously variable voltage transformer, having a single layer winding on a toroidal core of high grade Steel. In an autotransformer portions of the same winding act as both the primary and secondary winding. the winding has at least three taps where electrical connections are made. One end of the winding is usually connected in common to both the voltage source and the electrical load. The other end of the source and load are connected to taps along the winding. Different taps on the winding correspond to different voltages, measured from the common end.

What is a Servo Stabilizer ?
The Servo Stabilizers uses an advanced electronic servo-motor concept to control a motorized variable transformer. Output voltage accuracy is usually ± 2% with input voltage changes up to ± 50%. These machines are not affected unduly by power factor or frequency variation. This type of technology tends to be extremely effective when considering large three phase applications, as it is able to maintain its accuracy of all three phases, both line to line and line to neutral, irrespective of input voltage balance and load balance at any power factor. They are also able to withstand large inrush currents, normally experienced with inductive loads.
Various Design Topologies :
Single Phase Input & Single Phase Output ?
This type of servo stabilizer consists of an AC synchronous motor coupled with an Auto Transformer using gears. Now depending upon the input fluctuation, the servo motors adjusts the output of the Auto-transformer to provide a stabilized output. APEX uses embedded software in microcontroller for the control circuitry. Its application is where input supply & load output are single phase operated.
