BQXB-P Series Explosion-proof Frequency Converter, Explosion-proof Variable Frequency Starter Application Scope 1. Zone 1 and Zone 2 hazardous gas locations; 2. Class IIA, IIB T1-T4 gas or vapor environments; 3. Indoor and outdoor (IP54). BQXB-P Series Explosion-proof Frequency Converter, Explosion-proof Variable Frequency Starter Technical Features 1. Aluminum alloy shell or steel plate welding, surface plastic spraying; 2. Internally equipped with components such as frequency converters, circuit breakers, signal lights produced by companies like Fuji or Schneider; 3. It primarily adjusts the speed of ordinary three-phase asynchronous motors by changing its output frequency to meet production process requirements or achieve energy-saving purposes, with an energy-saving rate of up to 30% to 60%. It can also serve as a motor soft starter controller or form a closed-loop speed control system with sensors, transmitters, and other control circuits. It features simple installation and operation, constant power factor, and various functions such as fault display; 4. Equipped with multiple protections including overcurrent, short circuit, overvoltage, undervoltage, and phase loss. It can digitally display frequency, speed, load rate, or current, allow manual frequency adjustment, set process curves for speed changes over time, and receive signals from DCS systems to control its frequency; 5. Conduit or cable wiring.
