1�� Scope of application:

The BQXB series explosion-proof frequency converter (IIB) is suitable for hazardous areas in Zone 1 and Zone 2;
Class IIA and IIB explosive gas environment.

2�� BQXB series explosion-proof frequency converter (IIB) model meaning:

3�� Product features:

The BQXB motor variable frequency speed control box adjusts the speed of ordinary three-phase asynchronous motors by changing their output frequency to meet the requirements of production processes or achieve energy-saving goals. The energy-saving rate can reach 30% -60%. It can also be used as a soft start controller for motors, forming a closed-loop speed control system through control circuits such as sensors and transmitters. The installation operation is simple, the starting balance has no impact current (soft start), the power capacity is greatly reduced, the power factor is constant, and it also has various functions such as fault display.
1) Overcurrent protection, short circuit protection, overvoltage protection, undervoltage protection, instantaneous power outage protection, phase failure protection;
2) Digital display or indication or pointer display of frequency, speed, load rate or current, etc;
3) The frequency can be manually adjusted, the process curve of the speed changing over time can be set, and the frequency can also be controlled by a signal provided by the DCS system; This speed control frequency converter is an imported component. Inside the cabinet, there are also ammeters, voltmeters, automatic air switches, indicator lights, AC contactors, power frequency conversion switches, and start and stop buttons. Various appropriate operating methods can be designed, selected, and configured according to the process requirements of different users.
4) Both steel pipes and cables can be used for wiring.
5) Meets the requirements of GB3836-2000 and IEC60D79 standards.
