3Pcs CCM5D DC 6V-30V 16kHz Motor Speed Controller LED Digital Display 6-8A PWM Variable Speed Regulator With Shell

Features: CCM5D DC Motor Speed Regulator controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM). Large 0.56 inch 3-digit LED display numbers allow viewing under the most adverse conditions. The display range of 3-digit LED display is "000"-"100". ( For example, displayed "60" it means that the PWM output duty cycle is 60% ) Input supply voltage range: DC 6V-30V Rated current: 6A, Max 8A PWM frequency: 16kHz Adjustable speed range: 0%-100%. Incorporate a push key. Push closed, and then push open. Item size: 79 x 42 x 24mm Potentiometer: resistance B100K; cable length 20cm; open hole distance 8mm Operating instruction: WARNING: Before you attempting to wire the controller, make sure power is off. DO NOT REVERSE POSTIVE AND NEGATIVE POWER LOADS.THIS WILLDAMAGE THE CONTROLLER. TO CHANGE MOTOR DIRECTION, INTERCHANGE THE POSITIVE AND NEGATIVE WIRES OF MOTOR. 1. Connect wires refer to the "wiring diagram". 2. Turn on the power, and adjust the potentiometer. 3. The LED display displays the PWM output duty cycle. 4. Push the key, the controller closed, push it again, the controller open. Package included: 3 x DC motor speed controller
