Description
C-MH-18-790A-CM is a DC motor controller designed for multiple horsepower applications, supporting dual voltage operation with a 12A continuous current rating when properly heat-sinked. It incorporates SCR-based control, soft-start functionality, and precise speed regulation with adjustable parameters for torque, acceleration, and speed range. This controller is typically used with DC motors and gearmotors in industrial and commercial motion control systems.
Features
- Dual voltage operation for 90V and 180V DC motor applications
- 12A continuous current rating with appropriate heat sinking
- 2% base speed regulation with line voltage compensation
- Wide 50:1 speed range with constant torque capability
- Soft-start circuitry for reduced mechanical stress
- Integrated transient and surge protection
- SCR-based discrete power components for improved heat dissipation
- Power ON/OFF switch and status indication (enclosed models)
- Includes 5kΩ, 5W speed control potentiometer
- Flexible connection via screw terminal or plug-in terminal options
Design Notes
- External heat sink is required for high horsepower applications to maintain thermal stability
