20A 200W/400W 12V/48V Brushless DC Motor Controller BX-2

Generaler：

• Spänning:11V-55V.Current:Cont.MAX=20A (24V) Current protection:25A (24V)Max electric speed:240000 rpm (no HALL) 60000rpm (HALL)
• Hastighets kontroll model:open loop or close loop control(can set)Speed adjustable way:1.Internal potentiometer(spd2),reduce speed by rotating ccw and increase in CW.
• Speed adjustable way 2:Outer potentiometer.Add a potentiometer of 10K-20K between “SPD”och “GND”,or add a 0-5v power supply to adjust speed
  outer of “SPD”.It’s linear between speed and voltage.Normally,we select 1 which has a better result from above 2 ways.Please make a short circuit between
  SPD”och”GND”if need way 1 only.If need way 2 only,please rotate internal potentiometer to minimum in CCW.Start/Stop:Start if make a short circuit between
  RUN”och “GND”.Stop if open.
• CW/CCW:CCW if make a short circuit between “REV”och “GND”.CW if open.Speed signal:”PLS”is pulse output.3 pulse 1rpm.
  Pulse amplitude is +5V.(Notera:Rotor speed electric speed/poles[pairs])
• Protection function:Current protection,thermal protection,voltage protection,motor
  stall protection,starting protection,etc
