Tel: 0577-27770660 phone: 13105779166 QQ: 1991719168 Contact: Mr. Liu ACS150-03E-01A2-4 drive mainly by the rectifier (AC to DC), filter, inverter (DC to AC) , brake unit, the drive unit, a detection unit micro processing unit and other components. Internal IGBT inverter by breaking to adjust the output voltage and frequency power supply, according to the actual needs of the motor they need to provide the power supply voltage, and thus achieve the purpose of energy, speed, and in addition, there are a lot of drive protection , such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the drive has been very widely used. ACS150-03E-01A2-4 frequency energy saving drive mainly on the fan and pump applications. In order to ensure the reliability of the production, in the design of a variety of production machinery is equipped with power-driven, have left a certain amount of surplus. When the motor is not running at full load, in addition to achieve the power-driven requirements, the excess torque increases the active power consumption, resulting in waste of energy. Fans, pumps and other equipment of traditional speed control method by regulating the inlet or outlet of the baffle, the valve opening to adjust to the wind and to the water, the input power, and a lot of energy consumption in the baffle, the valve closure process in. When using the inverter, if the flow requirement is reduced by reducing the pump or fan speed to meet the requirements. Motor inverter role is to control, and reduce the starting current. In order to produce a variable voltage and frequency, the apparatus is first necessary to AC power is converted into direct current (DC), this process is called rectification. The direct current (DC) is converted into alternating current (AC) of the device, its scientific terms as "inverter" (inverter). General inverter is a DC power inverter for a certain fixed frequency and a certain voltage inverter. For the inverter frequency is adjustable, adjustable voltage inverter drive we called. Waveform analog sine wave inverter output is mainly used in the three-phase induction motor drive with, also known as the inverter. For the main instrument used in testing devices require higher wave variable frequency inverters, to sort out the waveform, you can output standard sine wave, called frequency power. Inverter power inverter is generally 15 - 20 times the price. Since the main means changing voltage or frequency converter device called generation "inverter", so that the product itself was named "inverter", namely: the inverter. ABB drives by ABB Group R & D, production and sales of well-known brand inverter. Mainly used to control and regulate the speed of three-phase AC induction motor, and its stable performance, rich combination of features, high-performance vector control technology, low speed high torque output, good dynamic performance and superior overload, In the inverter market occupies an important position.
