Speed Regulator Module for Automotive Air-Conditioning Systems

1. Introduction

The speed regulator module for automotive air-conditioning systems, produced by our company, stands as a pivotal component in regulating the performance of brushless fans across a diverse range of vehicles, including trucks, buses, and passenger cars. Utilizing advanced PWM (Pulse Width Modulation) square wave drive technology, this module facilitates smooth and efficient speed control, thereby optimizing the overall functionality of the air-conditioning system.

2. Technical Specifications

• Operating Voltage: The module is available in two variants: a 24V version operating within a voltage range of 20V to 32V, and a 12V version functioning between 8V and 18V. This flexibility allows for compatibility with various vehicle electrical systems.

• Rated Current: The 24V model boasts a rated current of 16A, while the 12V model delivers 25A, ensuring ample power to drive all compatible brushless fans on the market.

• Power Output: Both variants provide a robust power output of 400W, guaranteeing sufficient driving force for demanding air-conditioning applications.

• Signal Amplitude: The signal amplitude is tailored to match standard automotive electrical signals, with 24V for the 24V variant and 12V for the 12V variant.

• Operating Temperature: The module operates reliably at temperatures below 60°C, ensuring stable performance under diverse environmental conditions.

3. Protection Features

The module is equipped with comprehensive protection mechanisms to safeguard against potential operational hazards. These include:

• Fan Blockage Protection: Detects and responds to any obstruction in the fan's rotation, preventing damage and ensuring continuous operation.

• Over-Current Protection: Monitors and limits the current flow to prevent excessive current draw, which could lead to system failure.

• Over-Temperature Protection: Activates when the module's temperature exceeds safe limits, preventing thermal damage and ensuring long-term reliability.
