Where have u found the best place to buy your Meanwell PSU'smarquisite said:I originally had a 'Meanwell lookalike' 350W 24v PSU from eBay but it had big problems with generating electrical interference that would kill connection to the internet and display lines on screens using analog connections (VGA monitors, etc).
I now use an official Meanwell 320W 24v PSU (SP-320) that does not have these problems.. 2011 I will need a 2nd PSU so will stick with an official Meanwell as my problems put me off trying any generic copy cat brands.
The cable thickness causing volt drop issue is only a visible concern within your rig up until the point where there are multiple channels worth of current flowing through one cable - i.e. between a power supply and the controller. After you have passed the controller, what happens on other channels will no longer be able to affect the voltage on any particular channel so you wont see the unwanted random dimming problems due to the load from other channels.Silvo said:If i wanted to mount my power supplies close to my controllers, but mount my controllers in a single location (garaged), would the max achievable distance from the controller to the string just be dependent on the cable thickness of the lead to the string?
so if i mount everything central, and want to run a string 10 metres away i would likely use heavier cable to the string to not lose current.
I use Meanwell in our commerical controllers exclusively now, primarly because i have had very little trouble with them, they functional well, they survive dead shorts on the output well, they shutdown nicely if they get overheated. Electrically they seem stable, and they dont' produce lots of RFI. Yes, they are a little more expensive than some of the so called "copies", but like everything "yous gets whats yous pays fors"marquisite said:I originally had a 'Meanwell lookalike' 350W 24v PSU from eBay but it had big problems with generating electrical interference that would kill connection to the internet and display lines on screens using analog connections (VGA monitors, etc).
