Features

1. Multi-Stage Speed Control: The controller offers 4 to 6 programmable speed settings, with a PWM (Pulse Width Modulation) frequency range of 500Hz to 25kHz, allowing precise adjustment of fan RPM from 800 to 4500 RPM (±2% accuracy). This ensures optimal cooling for different engine loads and ambient temperatures.

2. Temperature-Responsive Operation: Integrated with a high-precision NTC thermistor (10kΩ ±1%), it automatically adjusts fan speed based on real-time temperature readings from 40°C to 120°C, with a response time of ≤200ms.

3. Power Efficiency: The MOSFET-based driver circuit achieves 95% energy efficiency at full load (12V/30A), reducing electrical system strain. It features overcurrent protection at 35A ±5% and operates within a 9-16V DC range.

4. Compact Design: The controller measures just 80mm × 50mm × 25mm with an IP65-rated aluminum housing that dissipates heat up to 15W without external cooling.

5. CAN Bus Compatibility: Supports SAE J1939 protocol for seamless integration with vehicle ECUs, transmitting data at 250kbps with ≤5μs signal latency.

6. Diagnostic Capabilities: Features built-in OBD-II compliant error reporting with 16-bit diagnostic codes, monitoring parameters like voltage ripple (≤100mVpp) and motor wear indicators.

Applications

1. Automotive Climate Control Systems
Car fan speed controllers are integral to modern HVAC systems, ensuring optimal airflow for passenger comfort. They adjust fan speeds based on cabin temperature, humidity, and user preferences, enhancing energy efficiency.

2. Electric Vehicle Battery Cooling
In EVs and hybrids, these controllers regulate cooling fans to maintain battery temperatures within safe limits. Precise speed adjustments prevent overheating, extending battery lifespan and performance.

3. Engine Cooling Management
Traditional combustion engines rely on fan controllers to modulate radiator fan speeds. This prevents engine overheating while minimizing unnecessary power draw, improving fuel efficiency.

4. Aftermarket Customization
Enthusiasts use programmable fan controllers for high-performance vehicles. Custom speed curves can be set to align with upgraded cooling systems or track conditions.

5. Commercial Vehicle Applications
In trucks and buses, robust fan controllers ensure reliable thermal management under heavy loads. They often integrate with telematics systems for predictive maintenance alerts.
