Description:

Features: CCM9NW DC Motor Speed Controller provides variable speed capability for DC motor. Adjustable speed range is 5%-100%. Three PWM frequency can be choose: 240Hz, 2. 2kHz, 22kHz; Suitable for the DC motor (or DC load) within 30A, Peak current 40A(max). The use of ambient environment temperature is -20(-4) to 40(104) potentiometer cable length 40cm. Operating instruction: Before you attempting to wire the controller, make sure power is off. WARNING: DO NOT REVERSE POSTIVE AND NEGATIVE POWER LOADS. THIS WILL DAMAGE THE CONTROLLER. TO CHANGE MOTOR DIRECTION, INTERCHANGE THE POSITIVE AND NEGATIVE WIRES OF MOTOR. 1.
