LED waterproof Power Supply used Pulse Width Modulation (PWM) switching technology,IP67 
specially designed for LED Neon flex outside design. It has advantages such as high 
Reliability, Stability, Efficiency and Lower Consumption. Compared with the regular 
transformer, it can save energy 50% at least.
Constant voltage power supply is the best choice for LED neon flex and Rope light
we can make the LED driver as below:
input voltage range from AC170-250V 
Watts range from:18W,30W,45W,60W,100W,150W,200W;
Output voltage range from DC12V,DC24V.
