1、ACCURATE AND FAST: The S6700H speed controller is an all electronic device. For instantaneous load changes, can respond quickly and accurately to control engine speed, which is closed loop control 2、WORKING PRINCIPLE: The basic characteristic of the governor is to adjust the starting fuel and speed fluctuation of the engine. This characteristic can make the engine reach the rated speed and output power under the condition of reducing the smoke emission, and maintain stability 3、VARIOUS PROTECTION: The S6700H speed controller has power back protection, actuator fault protection, loss of speed sensor signal protection. There are also overspeed protection and system fault input protection 4、TECHNICAL PARAMETERS: Voltage for 24VDC, actuator current range up to 10A, speed sensor signal from 1‑20V, rated frequency range from 1k‑5kHz 5、SCRATCH RESISTANT ABS: Electronic generator speed controller adopt excellent ABS material, possess impact resistance, scratch resistance, environmentally friendly 1 x Electronic Generator Speed Controller Item Type: Electronic Generator Speed ControllerMaterial: ABSVoltage: 24VDCWorking Environment Temperature: -40~80℃Relative Humidity: 95%Actuator Current Range: Up to 10ASpeed Sensor Signal: 1-20VRated Frequency Range: 1k-5kHzFrequency Fine Tuning Range: More than ±200HZ(external 5kΩ)
