5V 12V 10A Voltage Regulator PWM DC Motor Speed Controller Governor Stepless Speed Regulator LED Dimmer Power Controller _x000D_ Description:_x000D_ Max voltage: 16V_x000D_ Minimum voltage: 5V_x000D_ Continuous current: 10A_x000D_ Short maximum current: 20A (less than 10 seconds)_x000D_ Speed control mode: PWM stepless speed regulation, can also be used to adjust the light_x000D_ Control mode: speed control potentiometer (clockwise clicked open, continue to rotate clockwise from 1% to 99% speed)_x000D_ Duty cycle: 0%-99% (0% position is the state of the switch off when the potentiometer is most on the left)._x000D_ When the current is switched on, the 0.002A (long time no need to switch off the governor is no current)._x000D_ Efficiency: the maximum efficiency is as high as 98%._x000D_ Volume: long 3cm (excluding potentiometer), wide 2cm, high 1.4cm_x000D_ If you are using the speed control (dimming) to do the product, the shop can provide free_x000D_ Custom service, can be in accordance with the requirements of the customer to modify the shape of the circuit board, installation_x000D_ Mode, current and voltage parameters, add other functions, etc_x000D_ _x000D_ Note that the governor is mainly used in motor speed control, if you are used to LED dimming, must ensure that the LED can also work in direct power supply, the dimming range of the speed governor is from LED to LED directly connected to the power supply is completely extinguished between dimming, if LED is directly connected with a power that will burn through dimmer the dimming is burned, which typically requires a series current limiting resistor, if you don't know how much resistance can contact customer service._x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
