Dimmer 48v, DC Dimmer 12V, 24V, 36V, 48V, PWM Dimmer switch. PWM can be described as a dimming process which is common in LEDs using constant-current drivers. The method works by altering the frequency of the current, which results in variations to the average current within the string. PWM is a reliable method for achieving precise lighting dimming needs, as it is able to handle large dimming rates with a 100-Hz frequency (high frequency, which means that human eyes cannot see the flickering effects) without causing any harm to the color of the LED or the temperature. To dim the LED the LED has to be toggled at a rapid speed. For example, at the most extreme settings (full output) the LED remains "on" and is not turned off. When the dimming rate is 75 percent lighting, the lights are "on" 25% at a time. If plotted on graphs the shifts in current appear to be staggered similar to an evenly spaced set of blocks or stairs that do not have any long-term ascending or declining pattern (rates/values of increase/dips are constant).
This kind of dimming is perfect to light systems which have to be dimmed to less than 40 percent in a consistent manner. PWM is ideal for color mixing requirements because of its precise dimming characteristics. Additionally, it is used in electronic systems by directly digital controls.
DC dimming is superior to pahse dimming. DC dimming is better for the eyes. However, even at very low values, the flickering screen will not be visible for our eye. However, it can cause all kinds of discomforts. The PWM Dimming may cause discomforts such as headaches and eyestrain during the first phase. It may trigger migraines following prolonged exposure.

This dimmer can be application for constant voltage driver LED lighting, it adopted the most advanced PWM (pulse-width-modulation) digital brightness-adjusting technology that enables you adjust the brightness with the infinite knob and also can adjust the brightness far away with the IR wireless controller. It's ideal for installing sockets for commercial or household use that are style 86. It can be placed in the wall, or even hidden in the wall. It is capable of meeting different demands for brightness during various times by using the dimming. Also, it can extend the lifespan of LEDs and decrease power consumption. It is ideal for dimming high-power or lower-power LEDs.
