26 width ceiling suspending magnetic track light system

How does the magnetic track power the magnetic lamp? As we all know, the working voltage of magnetic track lights is DC48V, so it’s impossible to connect the track with 220V working voltage directly. The reasons are as follows: First, magnetic light lamp use 220v working voltage, it is easily damage the LED chip and cause a fire. Secondly, The track is made of aluminum alloy and has electrical conductivity. If directly input 200V, people will easily get an electric shock when installing the magnetic lamp.   Drive power is divided into external power supply and built-in power supply: The external power supply is installed outside the track. Similarly, the built-in power supply is installed inside the track. What is the difference between them? The external power supply has a larger wattage than the built-in power supply. led magnetic light is installed on the track and belongs to a series state. The wattage of the driving power supply must be greater than the to…
