Product Description
GAC Engine Speed Control Unit Speed Controller Droop Governor S6700E
 | GAC Engine Speed Control Unit Speed Controller Droop Governor S6700E spare parts petrol generator governor controller S6700E is PID adjustment design. It can instant and accurately reaction to the transient change of the loading then to make the engine speed in stable situation. It can perfectly control the engine speed by connected to the EFC series Electronic Acuator and Speed Sensor. This unit is design to easy installation and can pre-adjustment, including regulation rate and working idling. Different model of EFC series can controll kinds of output generator sets. |
 | The S6700E Speed control Unit is an All-Electronic Device Designed to control engine speed with fast and precise response to transient load changes. Based on a closed loop control. The basic characteristics of this unit is to reach rated speed and power as well as reducing smoke exhaust through adjustment of firing fuel and speed-rate. The S6700E speed control Unit provides a series of protection once the power supply is reversely connected. Transient overvoltage or actuator fault happens, or Speed input breaks. |
