Description 1.Working voltage: DC10V-DC50V wide working voltage range 2. Control power: 0.01-2000W (maximum rated current 40A) different operating voltages correspond to different control powers as follows; When the working voltage is 12V, 12V*40A =480W When the working voltage is 24V, 24V*40A =960W When the working voltage is 36V, 36V*40A =1440W When the working voltage is 40V, 40V*40A =1600W When the working voltage is 50V, 50V*40A =2000W 3.Quiescent current: 0.025A (when the working voltage is from DC10V to DC50V, the quiescent current will not exceed 25ma) 4.PWM duty cycle: 5%-100% 5.PWM frequency: 12khz 6.Working temperature: -20 -- 40 (ambient temperature - 20 degrees below zero to 40 degrees above zero) This governor is of industrial grade quality and can work stably in an environment below zero, generally a commercial-grade governor It is not possible to work stably below zero.
