Constant voltage dimmable LED power supply output is designed to convert AC voltage to DC voltage and with a fixed output voltage and output current variables. It is also a dimmer which allows adjusting the light intensity. There are various types of dimming interfaces available: 0-10V, DALI, DMX, and wireless RF / WiFi.
A power supply voltage remains constant output DC voltage and the current range of variables, which are suitable for the LED strip and LED ribbon with a constant input voltage.

Generally, the voltage can be available in 12VDC, 24VDC or 36VDC. To use LED dimmable power supply, you must ensure that you are dimmable LED lamps.
An LED power supply dimmable with DMX interface allows to receive a DMX signal, the control unit can be connected to via DMX512 bus, the capacity of each bus can be up to 512 to 512 lamp for that address.
LED Driver with DALI interface DALI allows it to receive signals, the control unit can be connected to via the DALI bus, the capacity of each DALI bus can be up to 64 lamps because it has 64 short address. In addition to a brief address, DALI also has 16 group addresses and 16 addresses scene.
To choose a reliable dimmable LED power supply, there are a lot of key parameters to consider. The first account power factor, which defines the percentage of power that do useful work. The second is efficiency, which defines how energy efficient a driver is.
