Description

DCM 30A 24V PWM DC Motor Controller

The DCM 30A, 24V DC Motor Controller is a versatile and high-performance pulse-width modulation (PWM) controller designed for efficient control of low-voltage DC motors and related loads. Engineered for flexibility and reliability, this controller provides precise management of motor speed, torque, and operational performance across a wide range of industrial and commercial applications.

Operating within a 6 to 24V DC supply range, the unit supports a maximum current of 30A, making it suitable for demanding motor control tasks. The controller offers both manual control via a potentiometer and signal-based control through a 0–5V DC input, enabling seamless integration into automated systems or standalone applications.

In addition to motor control, the DCM controller can be configured for lighting, heating, and temperature control applications. By connecting an optional thermistor sensor, the unit provides accurate temperature regulation within a range of 5°C to 130°C, making it highly adaptable for process control environments.

Selectable frequency modes (180Hz and 350Hz) allow optimisation for different load types, while built-in short-circuit protection ensures safe and reliable operation. Designed with a single MOSFET architecture, the controller offers enhanced durability and simplified operation for fixed-direction applications.

Compact, robust, and multifunctional, the DCM 30A, 24V is an ideal solution for engineers requiring flexible and efficient DC power control.

⚠️ Important Note on Rotation Direction:

Please note that while the controller can be configured for either clockwise (CW) or counterclockwise (CCW) rotation, this setting is fixed after configuration. The unit does not support real-time or dynamic reversal of motor rotation. This is by design, as the system uses a single MOSFET, which simplifies the circuitry and enhances reliability for fixed-direction applications.
