Descriptions:This motor speed controllercan support AC and DC input. Non-existent power supply polarity problems. Large heat sinkwith mounting holes. And with a wide range of support motor. It can be used to control most of the DC motor in the market.Features:Can support AC and DC input. Non-existent power supply polarity problems.Large heat sinkwith mounting holes.Ultra-high-power control. support 5A current.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.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 . This drive can't fit for the DC motor that DC resistance is <2 Ohm Equipped with a fuse protection and better performance.The high power limiting resistance is adopted to reduce the heating of the whole module and improve the working stability.Specifications:Voltage Input:15-160VDC ,12-110VAC Maximum current: 5A currentWeight:135gPackage Included:1 x Motor Speed ControllerNote: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..
