The presented device is a specific device, thanks to which you can get the current frequency at the output that you need. This equipment is used in almost all areas of life where electricity is required.
Advantages and features of the device
Frequency converters have certain advantages. It:
- saving electric energy;
- long service life of equipment;
- protection against any unstable power surges or very strong network load;
- reduction of electricity costs, as well as almost complete automation of the equipment;
-high degree of immunity to interference;
- the ability to manage multiple stations at once;
- protection against the influence of external conditions, in particular temperature differences.
Frequency converters provide rectification and smoothing of frequencies due to a certain number of capacitors. From the resulting voltage, a special generator creates the necessary current flow. It will have a given and acceptable frequency.
Varieties of devices presented 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. Moreover, these mechanisms often have a fan load.
3. General industrial. 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 we can distinguish the following:
- accelerated braking of the system, which ensures the safety of all its components in case of too high a voltage ;
- automatic start of mechanisms;
- registration of emergency situations;
- protection of equipment from the influence of high temperature or other negative factors.
Features of the correct choice of unit
In order for the current frequency converter to be effective, it is necessary to purchase the correct equipment option. First, determine the type of device and the power of the mechanism that will be connected to it.
You also need to pay attention to the 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 ability to install a control panel outside the building in which the equipment is located.
It is important not to forget about what rated output current the presented device can give. It should also take into account the additional functions of the device, on which its cost depends. It is important to decide on how to control the device (scalar or vector). Also consider such a parameter as the ability to adjust the frequency range. Also pay attention to the number of output signals and control inputs. A single-phase frequency converter is perfect for use in everyday life or for connecting low-power equipment.
