Dimmable power supplies are pertinent to LED lighting, a function used in numerous applications to control the brightness of the LED lights. Intelligent design systems for dimming can include domestic applications such as kitchens, bathrooms and also commercial applications including retail, architectural and cinemas. The dimming of LEDs is done by using a dimmable power supply that controls the current flowing through the LED or where the LEDs are turned on and off via pulse-width-modulation.
There are three main dimming functions of dimmable power supplies these include; 1~10VDC dimming, PWM signal dimming and resistive dimming.
Resistive dimming – 100K potentiometer, variable resistance across the internal control voltage from a driver therefore does not require an external voltage.
1~10VDC dimming – 1~10V source is applied to the driver, 1V control voltage approximates to 10% output voltage, 2V=20%, 3V=30% and so on.
PWM Signal dimming – PWM is also known as pulse width modulation; this is where an external circuit is used to control the average voltage to the dimming input.
We offer a dimmable power supply range with 3-in-1 dimming – This combines all of the other 3 types of dimming, PWM, 1~10VDC and resistive dimming.
