5 steps to find the right frequency converter-0

Everyday frequency converters prove their high level of energy efficiency and wide functionality. Many of us probably don't even realize how many different processes use them. Frequency converters are widely used, starting with ventilation systems in educational institutions right here in Latvia, ending with oil pumps in Saudi Arabia. In short, wherever it is necessary to control electric motors.

Like all electronic equipment, frequency converters cannot be used forever. Each equipment has its own lifespan. It often happens that an unforeseen accident occurs and electrical equipment fails. On deeper examinations, the specialist finds that the frequency converter is damaged.

Technicians have desperate questions: How long will the equipment be shut down? Is it possible to do without a frequency converter? Need to buy a new one? Sometimes it's enough just to repair by replacing parts. However, it often happens that repairs are not possible, because the necessary components are not available and you have to wait several weeks or even months to get them. If this option is not acceptable to the management of the company, then the damaged frequency converter must be replaced with a new one. But this process is not as simple as going to the store for bread. In the following article, we have put together 5 steps that will make it easier for you to replace a damaged frequency converter.
