 Model implication 

 Features 
 CBQ59 Motor Variable Speed ??box by changing the output frequency to regulate the speed of the ordinary three-phase asynchronous motor, in order to achieve the requirements of the production process, or to achieve the purpose of saving, the saving rate 
 30% ~ 60%, can also be used as motor soft start controller, sensors, transmitters and control circuit composed of the closed-loop speed control system. Install and operate, starting balance rush current (soft 
 Starting), greatly reduce the power capacity, power factor is constant, at the same time, fault indication. 
 Speed ??control inverter device is a monolithic computer, it has a strong function: 
 (1) over-current protection, short circuit protection, overvoltage protection, undervoltage protection, instantaneous power protection and Duanxiang protection. 
 2 digital or instructions or a pointer to display the frequency, speed and load rate, or current. 
 (3) you can manually adjust the frequency. Can be set to speed time-changing technology curve. Also be controlled by DCS system signal to its frequency. 
 Frequency of the governor of the product imported components. The cabinet is also equipped with ammeter, voltmeter, automatic air switch, lights, AC contactor, power frequency inverter transfer switch and start and stop button. Can 
 Different advocacy process designed to select the devices and the preparation of a variety of appropriate methods of operation. 
 (4) steel pipe and cable wiring. 
 (5) comply with GB3836-2000, IEC60079, GB12476.1-2000, IEC61241 standard request
