terminal block In the improvement of the intelligent degree of the terminal, the high-pressure frequency conversion speed control of the pump is adopted, which not only improves the process, but also improves the product quality. It is the requirement of energy-saving and economical operation equipment and is an inevitable trend of sustainable development. Many good speed controls for the pump. In the high-voltage frequency converter, in order to solve the electromagnetic interference and power between the terminal unit of the multi-level high-voltage inverter of the main control system of the unit series connected, the relationship between the unit power unit and the power is proposed to adopt the optical fiber. A method of connecting a PWM power drive signal.
