Features: Motor driver board 12-36V for DC power input , VCC positive power supply,GND power supply is negative. Pulse speed signal: high and low output . IC can not understand the information with the customer request This board has many functions such as stall for protection, enable control, over-current for protection, steering control and speed control signal. This driver board has many advantages including low consumption, high reliability and efficiency. Electrical wiring: three-wire brushless for DC motor, corresponding to MA/U, MB/V, MC/for W Tip: If you use a heat sink smaller than 60W and no additional heat sink, you must add a heat sink above 60W. If the driving efficiency of the heat sink is not reduced, excessive temperature will cause sexual damage Specifications: Operating voltage: for DC 12V-36V Operating Current: <=15A Driver Power: <=500W Speed Voltage: 0.1V-5V Operating Temperature:-40-85C Humidity: 90%RH Stall protection:Yes Enable Control: Yes Over-current protection: Yes Steering control: Yes Speed control signal: Yes Size: approx 63x42.5x17mm/2.48x1.67x0.67in Power terminal Out: VCC(positive power supply) GND(negative one) MC(motor phases for W) MB(motor phases V) MA(motor phase U) Set for the control side: GND control terminal ground VR the governor end 0-5V ZF reversing control for M tachometer pulse output EL enable control terminal Note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand. Please allow 0-1cm error due to the manual measurment. Due to different motor manufacturers to make the hall of hall line order does not necessarily follow the line on the board to match the sequence, need to be adjusted, please parents who pay attention If the line sequence wrong, does not boot properly, current, or start other phenomena not open, forced to use the drive plate will burn Package includes: 1x 12-36V 500W Brushless Motor Controller
