    Default Fuse rating

    What rating blade fuse is recommended between psu and controller? I have 2 350watt psu running into a e682 controller powering 16x 12v 100 pixel strings.

    Thanks

    Does not matter what the controller is powering. Your fuse needs to protect the wire going to the controller and the controller itself. Look at the controller spec to see the max it can use. Then make sure the wire you use can handle that load plus 20%. Then use a fuse that will protect the controller if the controllers load exceeds the controllers rating.

    according to the E682 specs, each of the power connection powers 8 outputs 32A per side so 64 A total. Your PS is only 30A max. I use E682s. I use 10 ga wire from the PS to the E682 but I use a 20A inline fuse. 10ga wire is rated fpr 30 A, 12ga is rated for 20A. Since pixels are so bright I run mine at 80% max using a Dimming curve in Vixen.

    pixel are approx 60ma on full white so theoretically at 100 pixel you could be at 6 amps however unless you run everything at 100% full white you won't reach that.
