It can monitor the temperature of the key components of the host and the internal environment temperature of the system. The PWM fan intelligently adjusts the speed to effectively prevent the system from overheating and causing the machine to "strike" on site; it adopts a 360° full contact electrical connection, which is highly air-tight, anti-corrosion and anti-oxidation High performance and dust resistance, to ensure the reliable operation of the system in various industrial harsh environments such as dusty, humid, high/low temperature, corrosion, etc.; the large clamping force of electrical parts improves the system’s ability to resist vibration and impact, and ensures that the equipment is vibrating The requirement of long-term reliable work under the environment.
