Frequency converters: features of use and device selection

The presented device is a specific device, due to which you can get the current frequency at the output that you need. This equipment is used in almost all spheres of life, where electricity is required.

Advantages and features of the device

Frequency converters have certain advantages. It:

- saving of electrical energy;

- Long service life of equipment;

- protection from any unstable power surges or very strong network load;

- reduction of electricity costs, as well as almost complete automation of equipment operation;

-high degree of immunity to interference;

- Ability to control several stations at once;

- protection against the influence of external conditions, especially temperature fluctuations.

Frequency converters provide rectification and smoothing of frequencies due to a certain number of capacitors. From the received voltage, a special generator creates the necessary current flow. It will have a given and acceptable frequency.

Varieties of the presented apparatus and their functions

Frequency converters are classified as follows:

1. Vector. They are often used in equipment that has rather difficult launch conditions, as well as where mechanisms can very quickly change their characteristics.

2. Pumping. Very often such frequency converters are used in industrial units. And these mechanisms often have a fan load.

3. General industry. The main areas of application of such equipment are production lines, as well as mechanisms that are able to adapt to different loads.

As for the functions of the device, here it is possible to single out the following:

- accelerated braking of the system, which ensures the safety of all its components in case of too high voltage ;

- automatic start of mechanisms;

- registration of emergency situations;

- protection of equipment from the effects of high temperatures or other negative factors.

Features of the correct choice of the unit

In order for the frequency converter to be effective, it is necessary to purchase the correct version of the equipment. First, determine the type of device and the power of the mechanism that will be connected to it.

Also it is necessary to pay attention to the overall dimensions of the unit. They depend on the purpose of the converter. For example, industrial devices are quite large. An important parameter is also the possibility of installing a control panel outside the building where the equipment is located.

It is important not to forget which nominal output current the given device can provide. It is necessary to take into account the additional functions of the device, on which its cost depends. It is important to determine the way the device is managed (scalar or vector). Also take into account such parameter as the possibility of adjusting the frequency range. Also pay attention to the number of output signals and control inputs. For use in households or connecting low-power equipment, the single-phase frequency converter is perfect for you.
