Servo stabilizer is a system, which provides stable Alternate Current (AC) output voltage where the input power supply voltage changes drastically. It protects the costly equipment from high and low voltage problems.A Servo Stabilizer is a Servo motor controlled stabilization system that performs optimum voltage supply using a Buck\Boost transformer booster that captures voltage fluctuations from input and regulates current to the correct output. An AC synchronous motor adjusts voltage in clockwise or anticlockwise direction and manages the output voltage with components like control card,dimmer,comparator, transistors, mocs, etc.
1. Dimmer (Variable Transformer)
It is normally round in the shape. Silicon CRGO toroidal core is used for the base & copper wire with specific turn ratio according to the capacity is used. The basic purpose of dimmer is to increase or decrease the voltage which is fed to the buck boost transformer. 50% of the output voltage is increased or decreased by dimmer only.
Let us take an example: If the input voltage is 160V, the dimmer will increase it to 190V & rest of the 30V (since 220V is required to run any single phase load) will be done by Buck Boost Transformer.
A Servo Stabilizer is a popular replacement for low high rating appliances used in both commercial and residential places, homes and industries that provides unmatched voltage supply to protect your fragile equipments. Servo has both single-phase and three-phase systems coming in Oil cooled and Air-cooled units.
A Servo Stabilizer is not just a voltage fixing system, but a completely reliable energy device that is advantageous over the traditional relay based stabilizer. We have quite a number of benefits of using Servo:
2. Carbon Brush
This is a moving part in servo stabilizer, it is fitted in the shaft to make the contact with dimmer. If the input voltage variation is very frequent, this carbon brush will erase early and customer has to replace it very frequently. That is why servo stabilizer manufacturers should use best quality carbon brush.
3. Servomotor (Synchronizing Motors)
Servomotor as the name suggests is the main part of servo stabilizer. The motor rotates the arm connected on the dimmer in clockwise or anti clockwise direction according to input voltage.Buck-Boost-Transformer.
4. Buck Boost Transformer
Contrary to dimmer it is in rectangular shape. Bobin is fitted with EI CRGO core. When the transformer structure is built, it is dipped in varnish tank for extra protection. This type of Insulating varnish also called transformer varnish is put on all the windings used in buck boost transformers to encapsulate them before the servo stabilizer is ready for regress testing. Transformer varnish enhances coil life and protects windings in the transformer from environmental exposure that would otherwise get damaged due to vibrations. This varnish can be used as a great insulator for any coil of wire. Though transformer is there in Isolation Transformer also, But it different from buck boost transformer.
5. Contactor
The function of contactor is to cut the output of any servo stabilizer if it exceeds a prescribed limit.
6. MCB, MCCB
The MCB is used to switch on /off the servo stabilizer and gives short circuit protection whereas MCCB is normally for overload protection.
7. Electronic Circuit
As the name suggests, it sends the signal to various parts of a servo stabilizer like motor, dimmer, etc., so it works according to that signal & does their part to correct the voltage.
