ESD5120 Electronic Speed Control Generator Governor


ESD5120 Electronic Speed Control Description

ESC5120 generator governor is a fully electronic closed-loop control design. It controls the engine speed with a fast and accurate response to instantaneous load changes. When connected to the matching electronic actuator and magnetic speed sensor signal, Controls a wide variety of engines. It is designed for high reliability and can withstand various electromagnetic interference in the surrounding area of the engine. In design, it is simple to install and pre-adjustable, including adjustable speed and working idle speed, to assist the input of multiple machines or special purpose machines, and to prevent reverse battery voltage, instantaneous pulse voltage, and short circuit of the actuator Failure and safety protection in case of loss of speed sensor signal or power.

The ESD5120 electronic governor is rugged and can be placed in a control cabinet or engine mounting box together with other special control equipment. If water, mist or condensate may come in contact with the controller, it should be installed fixedly. This will allow fluid to drain from the speed control unit.
