1.In the design, it is easy to install and can be preadjusted, including adjusting the idle speed and work, to assist for input multiple machines or special purpose machines, as well as to prevent reverse battery voltage, transient voltage pulse implementation of the shortcircuit fault and security in case of loss of speed sensor signal or power supply and so on. 2.Full closedloop control technology. Fast and accurate response to control engine speed 3.It is easy to install and can be preadjusted. For input multiple machines or special purpose machines. 4.The speed controller is a closedloop control of the entire electronic design. It responds quickly to instantaneous load changes and precisely controls engine speed when connected to the match. And it can control a wide range of engines with the implementation of espeed magnetic sensor signals Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-YJL official store
