The outdoor power supply 24v of Smarts can reach the megahertz level. The power loss on the switching power tube is reduced, the inductance of the energy storage inductor is reduced, and the energy storage power is increased.

Therefore, the conversion efficiency of the entire outdoor power supply 24v can be greatly improved, and its conversion efficiency can be as high as about 90%.

It can be clearly seen from the principle circuit diagram of the outdoor power supply 24v that no bulky power frequency transformer is used here.

In addition, because the operating frequency of the circuit is several orders of magnitude higher than the 50Hz power frequency in the linear stabilized dimming led power supply, the filtering efficiency is greatly improved, and the capacity of the filtering capacitor is also greatly reduced. These two reasons make the dimming led power supply have the obvious characteristics of small size and light weight.

led light class 2 power supply not only has a wide range of voltage regulation, but also has the advantages of good voltage regulation effect and high linear regulation rate.

In addition, there are two methods for changing the duty cycle: pulse width modulation and pulse frequency modulation. Moreover, there are many methods and technologies to realize voltage stabilization, and designers can flexibly choose various types of led light class 2 power supply circuits according to the requirements and needs of actual applications.
