Technical indicators: 
(1) Operating voltage: DC10V-DC50V wide operating voltage range

(2) Control Power: 0.01-2000W (maximum rated current of 40A) different operating voltages corresponding to different control power as follows; 

Operating voltage 12V, 12V * 40A = 480W

Operating voltage 24V, 24V * 40A = 960W

When working voltage 36V 36V * 40A = 1440W

When working voltage 40V 40V * 40A = 1600W

When working voltage 50V 50V * 40A = 2000W

(3) Quiescent Current: 0.025A (DC10V to DC50V operating voltage quiescent current will not exceed 25mA)

(4) PWM Duty Cycle: 5% -100%

(5) PWM frequency: 15kHz

(6) Operating temperature: -20 - 40 (ambient temperature of minus 20 degrees to 40 degrees above zero) the governor of industrial-grade quality, the environment can be below zero stability work, general commercial grade quality governor can not work in sub-zero stable. 

Board Dimensions: Length 90 mm, width 51 mm, height 32 mm (not including potentiometer adjustment part)
