The Technology concept of Differential wound linear regulator with Series Transformer in RED PHASE’S make Automatic Voltage Controller.
We are manufacturing Industrial type Automatic Voltage Regulators (Stabilizers/Rectifiers) using the differential wound Vertical Roller Type Regulators. Manufacturing LINEAR TYPE +/- Heavy Duty Regulators with rollers rolling on both the sides of the coil (as illustrated in the brochure enclosed). The size of conductor used is more than THREE TIMES than used in conventional design regulators. Being + type, the same winding is used for boosting the voltage on one side and bucking the voltage on the other side of the regulator. So, the rating of the regulator required is half of the conventional design regulator.
The losses of differential wound linear regulator should be 1/18th of the conventional type regulator and due to heavy section of copper used in our regulator, overall size is more and practically the losses of our regulator are 1/5th of the conventional type regulator.
The manufacturing material cost of differential wound linear regulator is almost more than THREE TIMES the cost of conventional design Regulator.
As per the Regulator design, the regulator is technically OUT OF CIRCUIT, When the input voltage is LOWEST/HIGHEST as per the voltage range of the stabilizer while in stabilizer with conventional brush type regulators, the regulator is maximum in the circuit and losses are maximum at LOWEST/HIGHEST as per the range of the stabilizer.
The Actual Efficiency of our stabilizer in running conditions at 100% Load for the (360-460 V) model will be 99.5% in comparison to less than approx. 95-96% of conventional type stabilizer for the Automatic Voltage Controller of similar rating.
