PWM Controller (Pulse Width Modulation) is an abbreviation for "pulse width modulation". PWM controllers send short charging signals to a rechargeable battery instead of a fixed output. The controller device determines the length of the signals and the transmission interval according to the energy in the battery. If the battery is discharged, the current signals sent by the device to the battery are long and continuous. However, when the battery is full, these signals are sent at short intervals of a few seconds. PWM is the most widely used device in the alternative energy sector due to its low cost. As Helind, PWM Controllers are one of the products we offer to our customers during the installation of power systems.
