Engine driver UX-52 AC 400W The front can be reversed. This saves the old-fashioned way of wiring forward and backward. He Ma a human nature. It provides more stability, more accurate driving and break function, then. Technical data: motor speed controller model: UX-52 MCU control - microprocessor control maximum engine power: 400W Voltage: 220V 50/60Hz LED digital display driver functions: soft start- soft start - slow acceleration slow deceleration start/stop left/right rotation dimensions: 100mm x 90mm x 60mm 1. 2. 3. The pause and re-ride function can be implemented during the transmission process. 4. The motor speed controller provides greater stability and a more accurate ride. 5. The speed control range is 90-1400 (rpm. Controller using digital MCU control technology, multifunctional design, accurate speed control with stable performance. Use the digital display menu option to quickly and conveniently change the setting. The display speed can be set according to the user's display needs, and the target display value can be converted automatically. It can realize slow acceleration and slow deceleration. It can be operated by panel and controlled za by external switch. Panel knob automatically adjusts to the highest speed, easy to adjust and control, safe. Lock protection function to prevent engine and regulator from burning due to blockage. (This function can protect against blocked rotation overload, ale cannot protect against unblocked rotation overload.) Increasing the function of circulation operations.
