The WPM-2137C is a filtered PWM DC motor speed control unit manufactured by Bodine Electric Company, designed for precise and efficient speed regulation of DC motors in industrial applications.

Key Features

• Pulse Width Modulation (PWM) control for smoother motor operation
• Filtered DC Output: Reduces audible noise, lowers motor temperature, and extends brush life
• Back EMF Feedback: Maintains speed regulation within ±2%
• User-Adjustable Pots:
  • Torque limit
  • Minimum and maximum speed
  • Acceleration time
  • Speed regulation
• Diagnostic LEDs: Indicate power status and current limit conditions
• Inhibit Function: Optional user-supplied switch for motor stop/start control
