Frequency converter 1~220V × 1~220V up to 1.1kW + pressure sensor AQUATICA (AVF-1.1M) (779702). PLEASE NOTE! The rated current of the connected electric motor must not exceed the rated current of the frequency converter by more than 10%! Application area: The frequency converter is used to control and protect pumping equipment in water supply and drainage systems. Thanks to its design, it provides a smooth start of the electric motor, maintains the set water pressure level in the system by changing the frequency of the input power supply, starts and stops the pump, and protects the pump from operation in critical situations. For ease of use, the converter is equipped with a liquid crystal display that shows real-time information about the pump operating mode. The main advantage of these frequency converters is the simplicity of settings, so there is no need to seek the help of specialists to start a domestic water supply system. Advantages: Provides constant water pressure in the system. Adjusts the "voltage/frequency" (V/F) parameters, which saves energy from about 20% to 60%. Smooth start and stop of the pump motor, which reduces the risk of water hammer. Pr...
