        Engine Speed Control Unit/ Speed Controller/ Electronic Governor ESD5111       






ESD5111series speed controller is a closed-loop control of the entire electronic design, it's instantaneous load changes quickly and with precision control in response to engine speed when connected to the match and the implementation of e-speed magnetic sensor signals can be Control of a wide range of engines.

It is designed to be highly reliable, the engine can withstand the surrounding area within the range of electromagnetic interference.
In the design, installation and a simple pre-adjustment, including the transfer rate and adjustable idle for assistance or for multiple special-purpose machine input, as well as to prevent reverse battery voltage, the transient voltage pulse, the actuator short-circuit fault And the loss of power or speed sensor signal of the security protection
