Constant voltage one is suitable for the LED lamp with a fixed DC voltage input and variable current input. Constant current one is suitable for the LED light with a fixed DC current input and variable voltage input.
RF wireless interface is a new dimming input interface that controls the dimmable driver with a remote. The remote sends out radio frequency signal. The LED dimmable driver has a built-in receiver which receives the signal and converts it to PWM frequency that is used for dimming. It is a perfect solution for intelligent home lighting control.
The radio frequency for different countries and areas are different, you have to choose according your country or area’s requirements. The remote and the receiver shall have the same frequency. The power supply receives the signal and converts to PWM frequency for dimming the connected LED lamps.
Single color, dual color and RGBW remotes are available to control corresponding LED dimmable drivers. And the remotes are Audio Transformers Manufacturers available with push button, touch control and rotary knob styles. Touch panel remotes allow full touch control with one finger for dimming, color control, and running effects.
A qualified dimmable LED power supply shall has following features. First is high power factor, which means the power that does useful work. Second is high efficiency, which defines how energy efficient a driver is. Both of them are the most important parameters. Third is wide dimming range, power supplies with full dimming range 0-100% are the best choice. Forth is smooth dimming with no flickering especially under a low brightness level. Many power supplies have flickering phenomenon when doing dimming operation, which may damage the led lamps or reduce its lifetime. Fifth is no buzzing noise. If a power supply has heavy noise when working, it is not good for the environment and human being’s health.
