DC Motor Speed Controller 3.7-24V 5A with Wireless Remote, PWM LED Dimmer Module

Remote PWM Dimming Speed Control Module. Key benefits and reasons to choose this module: - Precise PWM control for smooth dimming and speed adjustment, making it easy to fine tune lighting and small motor speed. - Wide input range from DC3.7V to 24V, providing broad compatibility with common battery and DC supply systems. - High-performance output with a maximum working current of 5A and reliable long-term continuous operation at 3A, suitable for many DIY projects. - Compact two in, two out wiring layout simplifies installation and makes wiring clear at a glance. - Stable operation and durable construction for consistent performance in repeated use. - Easy remote pairing and memory functions for convenient wireless control and flexible installation options. Technical specifications: - Product name: Remote PWM Dimming Speed Control Module. - Working voltage: DC3.7V to 24V. - Working current: maximum 5A, long-term continuous operation 3A. - Wiring method: two in and two out. Functions and operation: - Pairing: Press the learning button on the module once; the indicator light will flash and then stay lit. Press any button on a compatible remote control once. The module will flash to confirm successful pairing. - Call on function: Press the learning button 8 times to enable the call on function, and press the learning button 8 times again to disable it. The factory default is call on disabled. - Clearing paired remotes: Press the learning button 9 times to clear all learned remote controls. Wiring symbol descriptions: - DC-IN- : Connect to the negative pole of the power supply. - DC-IN+ : Connect to the positive pole of the power supply. - OUT- : Connect to the negative pole of the load. - OUT+ : Connect to the positive pole of the load. Practical use scenarios: - LED strip lighting dimmer: Smoothly dim 12V or other low voltage LED strips for accent, undercabinet, or display lighting while staying within the module current limits. - Hobby motor speed control: Adjust speed of small DC motors and fans used in model making, robotics, or small appliances where peak currents do not exceed 5A and continuous draw stays near 3A. - DIY lighting and control projects: Use in custom controllers, prototype boards, or retrofit projects that require compact wiring and remote dimming capability. Compatibility and installation notes: - Compact form factor and two in, two out terminals make the module easy to fit into enclosures and integrate into existing wiring. - Ensure the power supply voltage is within DC3.7V to 24V and that the connected load does not exceed the specified current limits. - The module supports pairing with compatible remote controls; some product variants may include a remote control. This module offers straightforward installation, dependable PWM performance, and convenient wireless control for low voltage lighting and small motor applications.
