Excelon Systems

We are one of the best Manufacturers, Suppliers and Exporters of Servo Voltage Stabilizers to safeguard the electrical and electronic installation against fluctuations in supply voltage. You can count on us to provide long lasting solutions for protecting the electronic equipment and machinery. Our Servo Voltage Stabilizers give a good regulated voltage even with very wide input voltages. These Servo Voltage Stabilizers protect the end equipment from very low or high voltages thereby increasing its efficiency.

We offer a wide range of Servo Voltage Stabilizers. Standard models are available off the shelf and any other capacities are manufactured as per customer specification in the least possible time. These Servo Voltage Stabilizers are required in any application that constantly guzzles high voltage. We offer the Servo Voltage Stabilizers with standard packaging. We have supplied Servo Voltage Stabilizers, ranging from 5 KVA to 300 KVA to DoT.

Principle Of Operation
Servo Voltage Stabilizers consist of Buck-Boost Transformers, where secondary is connected in series with the main input and the load. The primary is supplied by an Auto-Transformer driven by a servo-motor. The motor is driven by a solid state sensing and control circuit which senses output voltage.

If the output voltage deviates from the set value, it activates the motor to be driven in the appropriate direction. The voltage induced from the variable Transformer adds or subtracts the voltage in the secondary of Buck-Boost transformer to give the original set voltage. In three phase, systems are connected in star.
