Specifications: Voltage:DC 5V-16V Continuous Current: 10A Short maximum current: 20A (less than 10 seconds) Speed control mode: PWM stepless speed regulation, can also be used to adjust the light Control 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). Efficiency: the maximum efficiency is as high as 98%. Volume: long 3cm (excluding potentiometer), wide 2cm, high 1.4cm If you are using the speed control (dimming) to do the product, the shop can provide free Custom 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, Package include: 1 x DC Motor Speed Controller The merchant warrants that their products comply with all applicable laws, and are offered only if they comply with Joom’s policies and EU Product Safety and Compliance laws.
