How to select appropriate transformer for 12V LED Strips

How to select appropriate transformer for 12V LED Strips

Step 1:  Calculate the power consumption of the strip you want

            A:  Single Chip SMD3528    0.08watt / LED        if you ordered 1 reel(16.4ft or 5meters)  SMD3528 with 300 leds, then the power consumption will be 0.08*300=24 watt / reel.    if you ordered 5ft High Density SMD 3528 with 36 LEDs Per ft, then the power consumption will be 0.08*36*5 = 14.4watt

           B:  Side viewing SMD335    0.08watt / LED        if you ordered 1 reel(16.4ft or 5meters)  Side Viewing SMD335 with 300 leds, then the power consumption will be 0.08*300=24 watt / reel.   

           C:  Tri-Chip SMD5050   0.24watt / LED        if you ordered 1 reel(16.4ft or 5meters)  SMD5050 with 150 leds, then the power consumption will be 0.24*150=36 watt / reel.    if you ordered 12ft SMD 5050 Flexible LED Strips 18 LEDs Per ft , then the power consumption will be 0.24*18*12= 51.84 watt

Step 2: Choose the appropriate type transformer

          A:    Non-waterproof transformer, DC12V,  from 1AMP(12watt) to 8AMP(96watt)               http://www.ledlightsworld.com/led-power-supply-110220v-ac-to-12v-dc-p-117.html

         B:  Non-waterproof Heavy Duty Industrial Series Adapter,  DC12V, from 8.5AMP(102watt) to 30AMP (360watt)  http://www.ledlightsworld.com/heavy-duty-industrial-series-adapter-110220v-ac-to-12v-dc-p-129.html

         C: Waterproof LED transformer,  DC12V, from 2.5AMP(30watt) to 8.3AMP(100watt)   http://www.ledlightsworld.com/waterproof-led-transformer-ac110v-220v-to-dc-12v-p-167.html

Step 3: Select the right AMP

         A: if you ordered 1 reel SMD3528 with 300 LEDs (24 watt), and need a waterproof power supply, then check the Waterproof LED transformer, and choose 2.5AMP(30watt)

        B:  if you ordered 2 reel SMD5050 with 300LEDs  (total 0.24*600 = 144 watt) and just want one transformer to run, then can can choose the non-waterproof heavy duty adapter, and choose  15AMP (180 watt)

PS: The AMPs or Wattage of the power supply must higher than the actural power consumption,  e.g. for one reel SMD3528 led strip with 300 leds, the power consumption is 24watt, but we recommend you choose DC12V  3AMP  36watt power supply for it.
