24v 36v 48v brushless dc controller 15A 30A

I. Overview:
This controller has three manners of working: speed control, current control and open-loop control.
Control functions of braking, direction, enable, first-magnification, dual speed setting, etc. can be realized.
Maximum current limit can be adjusted.
0-5V signal control way for external potentiometer, interior potentiometer and external analog quantity and soft start function.
Time setting function for soft start.
Overcurrent protection function   
Overheating protection function 
When the temperature is too high, the speed controller will stop outputting and provide better safety for the moter and the speed controller.
High-speed control that full speed of one pole pair motor can reach 120000RPM
