Dimmable LED power supply with constant voltage output is designed to convert AC voltage to DC voltage with fixed voltage output and variable current output.It is also a dimmer that can adjust the intensity of light.Various types of dimming interfaces can be provided: 0-Wireless 10 V, DALI, DMX, and RF/WiFi.
Constant voltage power supply outputs fixed DC voltage and variable current range, suitable for LED strips and LED bands with constant voltage inputs.Typically, the voltage can be provided in 12VDC, 24VDC, or 36VDC.To use a dimmable LED power supply, you must ensure that the LED light is dimmable.
In order to control the dimmable power supply, a control unit is required to output a dimmable signal to it.Traditional signal 0/1-10 v and resistance.But they are not smart enough to fit large lighting projects.
Emerging dimming protocols such as DALI, RF, and RF/WiFi are becoming more and more popular.The dimmable LED power supply with the DMX interface is able to receive the DMX signal, and the control unit can be connected to it via the dmx5 12 bus, with a capacity of up to 512 lights per bus due to 512 addresses.All power supplies connected to the bus can be controlled separately or grouped.
The scene feature is also enabled for DMX.The LED driver with the DALI interface is able to receive the DALI signal and the control unit can be connected to it via the DALI bus because it has 64 short addresses and each DALI bus capacity can be 64 lights.In addition to the short address, there are 16 groups of addresses and 16 scene addresses in Dali.
Many key parameters need to be considered to select a reliable dimmable LED power supply.The power factor is considered first, and it defines the percentage of power to complete useful work.The second is efficiency, which defines the energy efficiency of drivers.
Both are the most important parameters.
LED drivers with higher power factor and efficiency will be more reliable.Another parameter that should be taken into account is the PWM frequency, which determines whether the driver has flashing and buzzing sound when dimming.Normally, high frequencies cause no flashing noise, and low frequencies cause flickering but no noise.
