DC Fans are widely used in many different fields for cooling programs. The 622L series is a reliable and efficient fan choice for applications demanding high performance cooling systems. This article will be discussing the application field and working principle of the 622L series.

Application Field

The 622L series is particularly suitable for server and telecom, LED lighting, ventilation fan and storage, monitor cooling, and many other applications. Thie series has a relatively high speed and pressure capability with a low noise level. Its wide operating voltage range makes it suitable for applications both DC and AC voltage supplies. The 622L series also has wide applications in electronic applications such as servo motors, navigation equipments, frequency control systems, cooling equipments, and medical equipments.

The fan is built with a single-chip microcontroller and has several features such as speed control, over-temperature protection, and a low noise output. It also features a low start voltage, an automatic restart after power failure, and a PWM input.

Working Principle

The 622L series has a variety of working modes. It can operate as a direct current fan (DC), as an alternating current fan (AC) with voltage input, as a pulse width modulated fan (PWM) with voltage input, as an AC/DC fan with voltage input, and also as an ultrasonic fan with ultrasonic waves. The fan is constructed with two main parts: the motor and the control circuitry. The motor is a DC motor with its winding core inside the shaft. The magnetic field generated by this winding core is used to rotate the fan blades.

The control circuitry consists of several components such as the controller, the power MOSFET, and the SCR (silicon-controlled rectifier). The controller is responsible for controlling the speed and temperature of the fan. The power MOSFET provides the fan with the required voltage input and is responsible for switching the fan on and off. The SCR is used to provide the fan with a safe operating current. The PWM input is used to adjust the speed of the fan.

The speed of a fan is variable depending on the application it is used for. The 622L series has a range of speed settings that can be adjusted to meet the needs of various applications. The fan also has a range of temperature settings that can be adjusted to provide protection in the case of overheating. The fan also has various protection features such as an automatic restart after power failure, and a mute setting for quieter operation.

The 622L series is an ideal choice for a variety of applications demanding high performance cooling systems. It is designed to provide reliable and efficient cooling solutions. With its wide operating voltage range and many features, it is a great solution for both DC and AC voltage applications.
