12/24v led power supply
1. Small size and light weight: Since there is no power frequency transformer, the size and weight are only 20 to 30% of the linear power supply.
2. Low power consumption and high efficiency: The power transistor works in a switching state, so the power consumption on the transistor is small and the conversion efficiency is high, generally 60 to 70%, while the linear power supply is only 30 to 40%.

Description
Compared with switching power supplies and linear power supplies, the cost of both increases with the increase in output power, but the growth rates are different. The cost of linear power supply is higher than that of switching power supply at a certain output power point. With the development and innovation of power electronics technology, switching power supply technology is constantly innovating. This cost reversal point is increasingly moving to the low-output power end, which provides a wide range of development space for switching power supplies.
