Can be adjusted by changing the output frequency of the ordinary three-phase asynchronous motor speed in order to achieve the requirements of the production process, or to achieve the purpose of saving, saving up to 30% to 60%, but also as a soft starter motor controllers, closed loop speed control system can be composed by sensors, transmitters and other control circuitry. Installation is simple, starting balance no impact on current (soft start), the power supply capacity is greatly reduced, the power factor constant, along with fault display and other functions. Shell is welded steel or cast aluminum alloy shell, the surface electrostatic spray; with over-current, short circuit, overvoltage, undervoltage, instantaneous power failure, broken equally self-protection; digital or pointer can show the frequency, speed and load factor, or current, etc; the product of adjustable speed drives for imported components, you can manually adjust the frequency, the speed can be set according to time-varying technology curve, but also by DCS system gives the signal to control the frequency;? pipe or cable wiring user if needs, please contact our engineering and technical personnel Order [Tips]: Due to the limited web publishing model, more specifications and prices please call 0577-62899880 or 15067778728, and the other can be used QQ: 329143369 Consulting ****** ************************************************** ********************** The company mainly produces: explosion-proof lighting distribution box, explosion-proof distribution box, explosion-proof power distribution box, explosion-proof power overhaul boxes, explosion-proof distribution cabinets, explosion-proof repair an electrical outlet boxes, explosion-proof operation column, explosion-proof junction box, explosion-proof junction box, explosion-proof magnetic starter, explosion-proof circuit breakers, explosion-proof control box, explosion-proof cable tray, explosion-proof lights, explosion proof floodlight, explosion-proof cast light lights, explosion proof lights within the field of light, water and dust-proof lights, explosion-proof ceiling, proof fluorescent lamp, explosion-proof plastic fluorescent lamps, explosion-proof road lights, explosion-proof platform lights, glare floodlights, explosion-proof flashlight, portable explosion-proof lighting, Explosion headlights, explosion union, explosion-proof fittings, explosion-proof flexible connection pipe, explosion-proof limit switch, explosion-proof switch, explosion-proof lighting switch, explosion-proof control button, explosion-proof latch, explosion-proof bells, explosion sound and light alarms, explosion-proof axial fan , explosion-proof air conditioners, explosion shook his head fans, explosion-proof exhaust fan, explosion-proof type and various non-standard proof box, support non-standard custom
