I bought a channel letter sign which was wired with led lights and am hoping to get it working. There are 14 modules in a chain.






What type of transformer or power source do I need? What else is necessary? Thank you in advance!!

Hi CMRIGHT

To figure our the type of transformer you need, you must refer to the module specification. This will tell you the required voltage and wattage per module.

All of our modules have a working voltage of 12V. You then multiply the no. of modules you are using by the wattage per module.

Eg. 14no modules at 12V, and 1.5w per module = 12v 21w.

Therefore you would need a 12v 30w driver to run the modules, IP rated according to whether you are locating internally or externally.

I hope this helps

Hello,

Regarding the transformer you need, you have to take the wattage of each led module, the quantity of led modules and the efficiency of the transformer (so to not overload) into consideration.

Here is the example:
0.7watt/pc led modules, R channel letter requires a total 14 pcs to light up, the optimised transformer you need will be 13watt ( 14*0.7w =9.8w, to optimised using the transform,you have to divid 0.8 for avoiding the overload problems,that means 9.8w/0.8 = 12.25w, 13w transform will enough to light up your solution effectivly and cost-effective).

More questions or more requirements, you can contact me by email (This email address is being protected from spambots. You need JavaScript enabled to view it.) or skype(alexchou1986) at your convenience.
