4. Functional Module Detailed Introduction

4.1 PWM Speed Control Function

• Reduce fan speed under low load temperature to cut power consumption and running noise;
• Automatically boost to full speed when equipment temperature rises to ensure heat dissipation capacity;
• Perfect match with intelligent temperature control mainboards of servers and industrial control equipment.

4.2 Pulse Tachometer Speed Sensor

• Real-time monitoring of fan working status;
• Automatic alarm trigger when fan stall, abnormal speed or failure occurs;
• Avoid equipment overheating damage caused by fan shutdown, greatly improve equipment operation safety.

9. Purchase & Matching Suggestion

• Matching voltage: Must use 10.8~13.2V DC power supply, rated optimal operating voltage 12V;
• Control matching: The host mainboard needs to reserve PWM control port and pulse signal detection port to realize full fan function;
• Installation suggestion: Install vertically or horizontally, avoid long-term operation in high-dust, high-humidity corrosive environment, add dust-proof net if necessary;
• Alternative models: If lower rotation speed or different airflow pressure is required, consult Sanyo Denki San Ace 40 series other model variants for parameter comparison.
