company news about LGT40N120B For Frequency changer

       LGT40N120 variable frequency drive VFD is a power control device that uses frequency conversion technology and microelectronics technology to control AC motor by changing the working power supply frequency of the motor. Inverter The inverter is mainly composed of rectifier (AC to DC) filter, inverter (DC to AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter adjusts the voltage and frequency of the output power supply by the open segment of the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, so as to achieve the purpose of energy-saving speed regulation.
