脉宽调制(A4H124-24FX P0973JN)是大多数通信系统中使用的调制过程或技术，用于将信号的幅度编码成另一信号(通常是载波信号)的脉冲宽度或持续时间，以便传输。虽然PWM也用于通信，但其主要目的实际上是控制提供给各种电气设备的功率，尤其是交流/DC电机等惯性负载。

脉宽调制(PWA4H124-24FX P0973JN)用于控制数字信号的幅度，以便控制需要电力或电能的设备和应用。从电压分量的角度来看，它主要通过快速循环数字信号的开和关阶段以及改变“开”阶段或占空比的宽度来控制提供给器件的功率量。对器件而言，这将表现为具有平均电压值的稳定功率输入，这是导通时间百分比的结果。占空比表示为完全开启(100%)的百分比。

A4H124-24FX P0973JN的一个非常强大的好处是功率损耗非常小。与使用模拟电位计调节功率水平以限制功率输出相比，PWM实际上是关闭功率输出，而不是限制功率输出。应用范围从控制DC电机和调光到加热元件。

Pulse width modulation (A4H124-24FX P0973JN) is a modulation process or technique used in most communication systems to encode the amplitude of a signal into the pulse width or duration of another signal (usually a carrier signal) for transmission. Although PWM is also used for communication, its main purpose is actually to control the power provided to various electrical devices, especially inertial loads such as AC /DC motors.

Pulse width modulation (PWA4H124-24FX P0973JN) is used to control the amplitude of digital signals in order to control devices and applications that require power or electrical energy. From the point of view of the voltage component, it mainly controls the amount of power provided to the device by rapidly cycling the on and off phases of the digital signal and changing the width of the "on" phase or duty cycle. For the device, this will appear as a stable power input with an average voltage value, which is the result of the percentage of on-time. Duty cycle is expressed as the percentage that is fully on (100%).

A very powerful benefit of the A4H124-24FX P0973JN is that the power loss is very small. In contrast to using an analog potentiometer to adjust power levels to limit power output, PWM actually turns off power output rather than limiting power output. Applications range from controlling DC motors and dimming to heating elements.
