Frequently Asked Questions

What is?

What is Static Inverter?

Static Inverters are devices that supply your critical loads with stable voltage and frequency by converting the DC voltage provided by the battery or rectifier in your system to 220 V AC voltage when there is no mains electricity. It is designed for the supply of electrical appliances such as TVs, refrigerators, computer systems, office devices such as servers and printers, electric motors and electronic devices.

What are the differences between Static Regulator and Servo Regulator?

Difference between servo stabilizer and static stabilizer

In other words, if you cannot decide whether to use a static regulator or servo regulator, see the difference between servo stabilizer and static stabilizer.

Servo Stabilizer

1- Product technology is old.

2- The correction speed is 80 V / sec. Sensitive to instantaneous voltage changes In sensitive devices, it usually fails.

3- It is insufficient in applications requiring motor type starting current.

4- Large and bulky structure.

5- Only voltage monitoring is performed with the help of digital voltmeter. For other measurements, special measuring instruments must be added.

6- As a result of correcting with motor, mechanical wear will occur in time. It needs repair in about 5-10 years.

7- There is no electronic protection.

8- Especially the idle energy consumption is very high.

9- Protection unit is optional.

Static Stabilizer

1- It is the latest technology product.

2- Correction speed 5000 V / sec (especially successful in feeding sensitive devices).

3- It responds to instantaneous peak current. Motor type runs smoothly in applications requiring high starting current.

4- It is 40% smaller in volume than servo regulator.

5- Their weight is 55% lighter than servo regulators.

6- Input and output current information is monitored from LCD panel.

7- Historical fault records can be kept.

8- Since it does not contain motor, it has endless life.

9- It has electronic protection system.

10- Loss is very low compared to servoregulators. So it saves energy compared to servos.

Why does the isolation transformer not shock?

In order to explain why the isolation transformer has not been hit, it is necessary to first understand what electricity is and what is the current. Electricity; Due to the potential difference between the two points, it can be expressed as the current flowing according to the resistance between the terminals. The potential difference between two points is actually voltage. One of the points is the reference point. That is, a reference point is required for the flow of electric current, which can be a reference.

The isolation transformer is grounded, the star point of the output side of the medium voltage (O.G) transformers in the city networks is generally grounded. In this case, anywhere in the world, the earth is the reference point for the mains voltage. For this reason, when you hold the active end of the electricity, your shoes, body resistance and the floor is wet according to the situation changes in severity varies by passing over the electric current.

How can it do that?

It is easier to explain why the isolation transformer did not crash, now. Secondary, output side references of the isolation transformers are again the other end of the transformer. In other words, the secondary of the isolation transformer with respect to the ground forms a very low reference. This means a very low potential difference or voltage, which means that the body resistance is too high at this voltage level so that very low current does not pass or no current passes, thus causing electric shock.

This does not mean that the isolation transformer will not shock people. If you hold both ends of the output side of the transformer, the isolation transformer will multiply depending on the level of the output voltage of the transformer because you have set a reference point. In addition, if the isolation transformer is grounded (connection of the isolation transformer secondary or one of the output terminals to the ground), in this case, as a reference point is created, electric shock will occur when the other end of the transformer secondary is held free.

If the current exceeds 5 mA, the human body feels an electric shock. Nowadays, isolation transformers are used in order to ensure the safety of children at home and their safety at home.
