Description

The 2CH 4-Wire LED Digital PWM Motor Speed Controller offers comprehensive control over DC motors and fans, specifically optimized for 4-wire PWM fan configurations within a 10V to 60V DC operating range. This unit provides precise speed regulation via Pulse-Width Modulation, ensuring optimal performance and thermal management. Its dual-channel architecture allows for independent control and monitoring of two separate fan systems, displaying real-time temperature data.

Integrated temperature sensing and a configurable buzzer alarm system provide essential feedback, alerting operators to critical temperature thresholds or fan stop conditions. This controller is particularly suitable for applications demanding consistent cooling or precise motor speed, supporting most 12-48V 4-wire fans adhering to Intel’s specifications. For higher current fans, direct power connection to the main supply is recommended to bypass the board’s 3A interface limit.

Key Features

  • Ultra-wide DC8-60V working voltage range for versatile power input.
  • Two-channel independent temperature control with alternate display (-9.9°C to 70.1°C measurement range).
  • Configurable switchable stop alarm function with external AC buzzer support (default off).
  • Fan interface pins support up to 3A current; larger fans require direct main power connection.
  • Adjustable control output range from 10% to 100% signal (actual fan performance dependent).
  • Rotation speed measurement from 10-9990 rpm with 10 rpm resolution.
  • Stop alarm triggers if fan speed falls below 375 rpm.
  • Supports 4-wire PWM fans conforming to Intel specifications; not compatible with 2-3 wire fans.

Applications

  • Industrial UAV cooling systems for onboard electronics.
  • Custom drone builds requiring auxiliary fan control for thermal management.
  • Robotics platforms needing precise DC motor or fan speed regulation.
  • General electronics projects for temperature-controlled fan operation.
  • Server rack cooling or enclosure ventilation systems.

Frequently Asked Questions

What types of fans are compatible with this 2-channel PWM controller?

This controller is specifically designed for 4-wire PWM fans that comply with Intel's specifications, supporting most 12-48V models. It cannot control 2-wire or 3-wire fans. Ensuring compatibility with your fan's wiring and voltage requirements is crucial for proper operation and to prevent damage.

What is the operational voltage range, and how does it relate to fan power?

The control board operates within a wide DC8-60V range. However, the fan's power supply voltage must match its specific requirements, as the controller shares power with the fan. Incorrect voltage can damage the fan. Always ensure the supply aligns with your fan's needs.

Can I completely shut off a connected fan using this controller?

No, this controller, designed for Intel's 4-wire fan specifications, does not support completely turning off connected fans. Its output range is 10-100%, meaning fans will always run at a minimum speed. For applications requiring full fan shutdown, a different type of controller would be necessary.

What are the current limitations for fans connected directly to the board's interface pins?

While the controller's overall capacity is not limited by fan current, the on-board interface pins have a maximum current rating of 3A. For fans requiring more than 3A, their power supply must be connected directly to the main power source, bypassing the board's pins.
