So i got this 12/24v transformer. i want to hook up some leds to it but dont know what ones. i found some 24v led panels on dealextreme.com but dont know if they will work. here is a pic of the xformer and a link to the leds. 28W 6500K 2800-Lumen 28-LED White Light PCB Board (24V) - Free Shipping - DealExtreme 28W 3200K 2800-Lumen 28-LED Warm White Light PCB Board (24V) - Free Shipping - DealExtreme
That looks like it should work. I would throw some overcurrent protection in there as well just to be safe. Also have you connected the transformer to see if it puts out the correct voltage when configured correctly. I would recommend this to anybody using a used transformer as the windings might be opened or shorted out. Other than that I would say it should work. Personally, I would wire a disconnect somewhere in between the transformer and the led panel. You could probably wire more of the panels together if you wired them parallel off the transformer.
I'm also assuming those Led panels are AC rated as I can not tell by the specs on the page. You might want to contact the company before you order. Most LED applications are powered by DC. Your current transformer is an AC transformer.
thanks guys. ill keep adding info. gotta go talk to dad now. he is the electrician that got it ready for me.
well dad the master electrician said that the led wont care about the ac because the diode will cut the wavelength in half. so it wont matter if its ac or dc. this transformer is rated for 30amps and 750w. should i be installing a resistor for the panels? it will take 23 of these panels to fully load the transformer. 23x28w= 644w or 30A/1.3A=23.076 etc,etc. 23panels at 1.3amps=29.9amps
That is one big xfmr. Get yourself a bridge rectifier that will handle about double the current (for safety) and a big ass filter cap. At least 10,000 MFD @ 50 volts. That will give you filtered DC @24 volts. Those parts should cost no more then $10.
