PPD115A01 controller

Climate change and energy issues are currently prominent global challenges, and the efficient utilization of energy has become an important issue in our new era. On the path of green development, Lenz is not only a pioneer in reducing carbon footprint, but also a participant and contributor. Especially for the industrial field, the birth of the i-series MOTEC frequency converter is particularly crucial. Using the intelligent EASY System Designer for driver selection, the i550 MOTEC can save up to 30% of energy. The Lenz product with integrated regenerative feedback mode can achieve very high energy efficiency - which means there is no need for additional hardware costs such as braking resistors, and regenerative energy can automatically run back to the power grid.

Energy saving effect: The new Kerui frequency converter is used in the main fan to control wind speed, effectively changing the output of air volume and pressure, achieving the goal of energy conservation. The use of a fan as a frequency converter load device directly affects the speed of the fan. From the perspective of fluid science, the relationship between rotational speed and flow rate is proportional, the pressure of the fluid is proportional to the square of rotational speed, and the shaft power P is proportional to the cubic power of rotational speed. From the practical effect, it can be seen that the speed of the fan has been reduced by half,

 and the natural energy consumption has also been reduced by one eighth, indicating that the gearbox has achieved energy-saving of the main ventilation fan. Moreover, most coal mines use a fan to drive two motors, so based on this feature, one frequency converter can simultaneously control the normal operation of both motors. Regardless of the driving method used to control the power of the frequency converter, the total power cannot be smaller than the sum of the two motors.

In short, during the maintenance of high-voltage frequency converters in summer, attention should be paid to the temperature of the installation environment of the frequency converter, and the internal dust of the frequency converter should be regularly cleaned to ensure the smoothness of the cooling air path. Strengthen inspection and improve the surrounding environment of frequency converters, motors, and circuits. Check whether the wiring terminals are tightened to ensure the correct and reliable connection of all electrical components. Prevent unnecessary shutdown accidents from occurring.
