The main criteria for choosing a frequency converter.
What is a frequency converter?
This is a device that is designed to adjust the frequency of the output voltage. This is required in order to change the speed of rotation of the engine. The standard oscillation frequency is 50-60 Hz. With a frequency converter, this indicator expands to 0.5-800 Hz. At the same time, for most modern engines, the limit is 400 Hz. In order to purchase high-quality electrical products, contact only trusted suppliers. These include, for example, "Ital Techno".
How to choose the right model?
First of all, you need to pay attention to power. Focus on the maximum energy that the motor consumes. The aggregate index should be greater than this value by about 10%. This will make reloading impossible. If you want to choose a suitable solution from a wide range of options, then go to the site https://ital-tecno.com.ua/ . Also, there will always be a reserve power reserve. If several motors are connected to the converter at once, then it is necessary to sum up their power.
Also pay attention to the mains voltage. The larger the specified range, the better. Pay attention to the number of input phases. Three-phase models are installed on industrial equipment with a power of 380 V. Single-phase options are only used when connected to a standard network (220 V).
It is important to start from the right way to manage. Vector-type models are more expensive, but they provide the ability to choose fine settings. Scalar control is much simpler. It allows you to choose the ratio between the output and input indicators.
What else should I pay attention to when choosing?
The number of output and input signals is of particular importance. They increase the possibilities for configuring and controlling the inverter. Signals can be:
- digital;
- analog;
- discrete.
In addition, it is necessary to take into account the scope of the device. In most cases, models have standard case protection. You can choose an option that will be used, for example, in the mining industry. Here it is necessary to select a model that meets the standards of protection. It is usually labeled "IP". The higher the number, the better the equipment is protected.
Pay attention to the equipment for which the converter is intended. There are branded models that are used with the equipment of a particular brand. It is recommended to choose universal models for multi-purpose use.
