12V/24V 8A 100W/200W Brushless DC Motor Controller BX-1

Generals：

• Voltage:11V-28V. Current: Cont.MAX=8A (12V/24V )Current protection:9A 12V/24V)Max electric speed:240000 rpm (no HALL);60000rpm(HALL)
• Speed control model:open loop or close loop control(switch to select]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 between “SPD”and “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”and “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”and “GND”.Stop if open.
• CW/CCW:CCW if make a short circuit between “REV”and “GND”.CW if open. Speed signal:”PLS”is pulse output. 3 pulse 1rpm. Pulse amplitude is +5V.(Note:Rotor speed electric speed/poles[pairs])
• Protection function:Current protection,thermal protection,voltage protection,motor stall protection,starting protection,etc.
