The DC Brushless Electronic Fan is driven by PWM control technology. According to the temperature change, the fan speed is fully intelligently controlled, the consumption is low, the air volume is high. It has two functions of air blowing and pumping. It uses high temperature resistant material (above 125 °C) and specific electrical accessories, which has superior performance. It has high continuous operation stability and large loading capacity. It is with intelligent temperature control. The speed is divided into six gears, and the temperature is proportional to the speed. It has overcurrent protection, overvoltage protection, low voltage protection, phase loss protection, locked-rotor protection, and reverse connection protection.
