Frequency converters are extremely popular devices designed to regulate the speed of electric motors, significantly reduce starting currents, and save electricity during their operation.
Among the most common manufacturers of frequency converters, companies Siemens and Mitsubishi stand out. Both brands produce high-quality products that have proven themselves well in such areas as ventilation, water supply, machine engineering, and various industrial and household systems. When choosing an inverter from a specific manufacturer for particular needs, it is important to consider their features and advantages.
Features of Siemens frequency converters
- Ease of installation and setup.
- High compatibility with various third-party automation systems and software.
- Wide range of connections to control systems.
- Flexibility of settings and the possibility of combining with devices from other manufacturers.
Features of Mitsubishi frequency converters
- Function of significant noise reduction from the operating motor.
- Control panels in Russian, making settings easier.
- Overload protection systems that withstand up to 200% overload; continuous monitoring of parameters with instant output current limiting when exceeded.
- Reduction of electricity consumption by up to 10%.
- Automatic restart of the electric motor during power failures.
- Wide range of power ratings for electric motors from 0.2 to 630 kW.
How to choose a frequency converter
A frequency converter is necessary not only to extend the lifespan of electric motors, reduce the risk of failure, and save electricity but also to lessen the load on maintenance personnel. In specific situations, various factors may become primary when choosing equipment, so there is no universal answer to the question "what to buy?".
Before making a final choice of model, it is important to consult with specialists to avoid mistakes. For example, it may turn out that the selected model is incompatible with the automation used at the enterprise or is not designed to operate in a certain climatic environment. There are many nuances that may not be taken into account when choosing independently. Therefore, it is strongly recommended to consult experts for detailed advice before making a purchase.
