DMX LED driver is an clever capacity supply which integrates DMX dimming interface. A capacity supply means a device converts AC voltage input to DC voltage output. DMX is a digital addressable lighting manage interface which can domicile each device in the system. It is a perfect answer for big lighting projects.
A DMX govern system requires a master controller that sends out DMX signal, slave controllers that get the signal. A DMX driver is a slave. A master controller can be a console or a PC interface software. Each DMX system has 512 addresses, hence a master is bright of controlling max. 512 slaves. It with supports activity and scene control. Each slave can be configured to a action and every slaves in the similar activity can be controlled synchronously and substitute groups can be controlled separately.
The input voltage of a DMX LED driver can be stand-in depending on swing requirements of various countries and areas. Generally in North America area, a broad input voltage range will be required, such as 100-277VAC. And in Europe, a narrow input range is ok, such as 200-240VAC. The output can be constant current or constant voltage to fit swing types of DC LED lighting. The constant current report can be used for LED downlights and LED panel lights, and the constant voltage savings account can be used for DC LED strip lights.
The master DMX LED controller sends out DMX signal to the slaves (DMX LED drivers), the drivers convert it to PWM to dim the united LED light. The maximum cable length from master to salve can not exceed 300m.
Once you know how the DMX LED driver works, next how to pick a well-behaved one? There are some tips for your insinuation as follows:
Power factor and efficiency are the first to consider. faculty factor is parameter that defines the facility that does useful work. Efficiency is parameter defines how vivaciousness efficient a driver is. Both of them are the most important parameters. The driver later than well along skill factor and efficiency will be more excitement efficient and keep more capability bills.
Flickering and noise are the second to consider. back a dimmable driver will always be used to dim the brightness of linked LED light. Flickering is not allowed past it will be harmful to human eyes. Using a smart phone to take video of the vivacious with dimming will encourage you to check whether it is flicker forgive or not. Noise may caused by tall ripple current or PWM frequency. A silent LED driver shall have low ripple current or PWM frequency.
