Frequency BQX52 series explosion-proof box (Ⅱ B) 
 Scope 
 1.1 Zone 2 dangerous places. 
 2. Ⅱ A, Ⅱ B explosive atmosphere. 

 Features 

 BKX52 Motor Variable Speed box can change its output frequency to adjust the speed of an ordinary three-phase asynchronous motor, in order to achieve production requirements, or to achieve the purpose of saving, saving rate 
 30% to 60%, also can be used as soft-start motor controller, also available with sensor and control circuit loop speed control system. Installation is easy, no impact on the current balance (soft 
 Start), power capacity could be greatly reduced, constant power factor, fault display and other functions. 
 As the core of governor device is chip microprocessor, has a strong functions: 
 1. Over-current protection, short circuit protection, over voltage, under voltage protection, instantaneous power failure protection and Duanxiang protection. 
 2. To digital display or pointer display the frequency, speed and load rate and current. 
 3. You can manually adjust the frequency. Can set the speed by the time the characteristic curve. DCS system may also be given the signal to control its frequency. 
 Speed frequency of the product imported components. Cabinet is also equipped with ammeter, voltmeter, automatic air switch, light, AC contactor, the frequency adjusting signal and start and stop buttons. Can 
 Depending on the support of the technological requirements of the design, selection and preparation of a variety of devices suitable method of operation. 
 4. Pipe or cable wiring. 
 5. Meet GB3836-2000, IEC60079, GB12476.1-2000, IEC61241 standard request.
