and Primary Purpose: The speed control unit is a fully electronic device designed to control generator speed to respond quickly and accurately to ient load changes. Closed Loop Control: When connected to a proportional electric actuator and supplied with a magnetic speed sensor signal, the engine be controlled in or droop mode. Well protected: Protection against reverse battery voltage, ient voltages, accidental actuator short circuit, speed sensor signal or loss of battery charge. Working range: power supply voltage is DC12V, frequency setting range is 1000-7000Hz, speed sensor signal range is AC1-50V, 85-8500Hz. Plastic shell: The generator controller shell is made of plastic, which has toughness, wear resistance, aging resistance and . Project Type: Generator Speed Regulator Model: ESD2210-12 Power supply voltage: DC12V Maximum output current: DC 4A Frequency setting range: 1000-7000Hz Speed sensor signal range: AC1-50V, 85-8500Hz External frequency adjustment range: ±300Hz Idle speed adjustment range: set speed -3800Hz to -1300Hz Colour:Black Material:plastic Package Contents: 1 x Generator Governor Control Panel Only the above package content, other products are not included.
