<p>Features: 1. with the abnormal overload protection and current protection function</p> <p>2. Speed can be adjusted by VR port. Speed control mode: one is voltage control: give VR port input 0 to 5v voltage.</p> <p>3. Has the locked-rotor protection function, if Motors can not start within 5s repeatedly, module stop output. Adjust voltage VR port to 0v or power off, the protection status can be removed</p> <p>4. The function of the speed pulse signal output, M port, read the rotational speed of the machine. Depending on the motor each circle of the output pulse number is different.</p> <p>5. Enable function, EL port, High level (5v) motor work, low level (0v) motor stop.</p> <p>If motor less than 60W,not need heat sink, more than 60W must be add heat sink, without heat sink reduce the driving efficiency, the temperature is too high bring permanent damage!</p> <p>Working voltage: DC 36V-72V</p> <p>Working current: \u226415A</p> <p>Drive power: \u2264700W</p> <p>Speed regulating voltage: 0V-5V</p> <p>PWM control of motor speed frequency: 1KHz--10KHz</p> <p>Work temperature:-40---85\u2103</p> <p>Work humidity: \u226490%RH</p> <p>Set: A NO Hall Version</p> <p>Material: PC+metal</p> <p>colour: green</p> <p>Package Contents:</p> <p>1 x Drive Board(NO Hall Version)</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
