Major Differences Between Static Voltage Stabilizers and Servo Voltage Stabilizers

Having the correct idea of a product empowers you to make the right choice. While purchasing a stabilizer, you may get confused which one is better, servo voltage stabilizer or static voltage stabilizer? To help you not get in such confusion, we will discuss with you the main differences between a servo voltage and static voltage stabilizer.

Correction Time

A static voltage stabilizer's low rectification time is 20 to 30 milliseconds. It is because of the high voltage correction speed. On the other hand, a servo stabilizer's adjustment time ranges from 50 milliseconds to 5 seconds.

Auto Bypass facility

You can find it easy to give auto bypass facility in the static voltage stabilizer. Furthermore, this type of stabilizer can exchange to bypass without breaking the voltage of the output.

When it comes to servo voltage stabilizer, it can be tough for you to give auto bypass system into it. Even if you give the bypass facility, it won't be an ideal thing.

Voltage Correction Speed

There is no moving part in the static voltage stabilizer. You can find an electronic circuit in it to change the voltage in this type of stabilizer. This way the high voltage redress of static stabilizer is higher than of a servo one. The range of voltage redress rate can be from 360 to 50 voltages per sec.

On the flip side, you get a moving servo engine in the servo voltage stabilizer. It helps this stabilizer to accomplish rectification in voltage. This stabilizer is an electromechanical gadget. This way the voltage rectification speed of it is slower than of a static voltage stabilizer.

Maintenance

As mentioned above, there is a moving engine in the servo voltage stabilizer. There can be some tears in it, so there is need of proper maintenance. A static stabilizer has a static voltage regulator. Hence, it does not need maintenance.

Protection

A DSP control board is responsible to sense the input and output voltages constantly in the static voltage stabilizer. IGBT current and burden present play a significant role in operating this stabilizer. If there is a short out at output of this stabilizer, you can find the current increasing high. DSP does the job of sensing it and it cuts output. IGBT power stage also gets switched off by it. It helps in clearing the over current shortcoming.

This way a static stabilizer can clear the over current shortcoming rapidly. You don’t need to include any additional equipment in it for the same.

The case is not same with the servo voltage stabilizer. Hence, to clear the over current shortcoming you have to use an additional equipment such as MCCB, CB or any other.

Reliability

In servo voltage stabilizer, you can fix the voltages by expanding or diminishing the number of twisting. It is done with the help of shaft of servo engine. This way the voltages get increased and decreased in the transformer. So, a servo engine is responsible for controlling voltages in this type of stabilizer.

On the other hand, having good quality of IGBT power stage makes a static voltage stabilizer reliable. In general static IGBT power is better than electromechanical servo engine. It makes the static stabilizer more reliable than a servo voltage stabilizer.

So, these were some differences between a static voltage stabilizer and servo voltage stabilizer. Hope it was helpful. You can share your views with us in the comments.
