Descriptions: <br>This motor speed controller can support AC and DC input. Non-existent power supply polarity problems. Large heat sink with mounting holes. And with a wide range of support motor. It can be used to control most of the DC motor in the market. <br> <br> <br>Features: <br>Can support AC and DC input. Non-existent power supply polarity problems. <br>Ultra-high voltage scope, support 15-160VDC Input, support 12-110VAC input. <br>Large heat sink with mounting holes. <br>Ultra-high-power control. support 5A current. <br>Except the board inside a PWM speed control, can also support an external PWM signal input speed control, external PWM input requirements: level 3.5-12V VPP, the frequency of 1K-10KHZ, the duty ratio is 0% to 93%. in particular apply in MCH3 spindle speed control. when with external PLC control, a 2K resistor is used. <br>A wide range of support motor. It can be used to control most of the DC motor in the market. As long as the DC resistance of the motor is > 2 Ohms DC resistance . <br>The conversion rate is about 97%, and the power of the plate is different when the voltage is different. 160VDC,2A motor load, limit no more than 2W. <br>This drive can't fit for the DC motor that DC resistance is <2 Ohm <br> <br>When the control board is equipped with DC Motor, following conditions must meet: current<5A, resistance>2R, Voltage <110V <br>Equipped with a fuse protection and better performance. <br>The high power limiting resistance is adopted to reduce the heating of the whole module and improve the working stability. <br> <br> <br>Specifications: <br>Voltage Input: 15-160VDC ,12-110VAC <br> <br>Maximum current: 5A current <br>Weight:135g <br> <br> <br>Package Included: <br>1 x Motor Speed Controller <br> <br> <br> <br>Note: <br>Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.<br>1、Can support AC and DC input.
