Specifications:Voltage:DC 5V-16VContinuous Current: 10AShort maximum current: 20A (less than 10 seconds)Speed control mode: PWM stepless speed regulation, can also be used to adjust the lightControl mode: speed control potentiometer (clockwise clicked open, continue to rotate clockwise from 1% to 99% speed)Duty cycle: 0%-99% (0% position is the state of the switch off when the potentiometer is most on the left).When the current is switched on, the 0.002A (long time no need to switch off the governor is no current).Efficiency: the maximum efficiency is as high as 98%.Volume: long 3cm (excluding potentiometer), wide 2cm, high 1.4cmIf you are using the speed control (dimming) to do the product, the shop can provide freeCustom service, can be in accordance with the requirements of the customer to modify the shape of the circuit board, installation Mode, current and voltage parameters, add other functions, etc..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.Package Included:1 x DC Motor Speed Controller
