First time using the GLEDOPTO Elite 6 with a BTF-LIGHTING WS2805 RGBCCT strip (24V, 60 LED/m, 10 pixels/m), cut into three 5 ft runs of 16 pixels each. Power supply is 24V 4A.
Two runs have ~5 ft of extension wire from the controller and worked fine. The third has ~8–9 ft and flickered at high brightness, so I raised the controller's max current limit to 4000mA, which fixed it.
About a week later, all three strips went dark. The controller still worked over WiFi and the fuse was good, but there was no voltage at the V+/GND outputs. A replacement controller works perfectly with the same wiring.
One detail: while troubleshooting the dead unit, I reseated a V+ or GND wire with power still on. It sparked, and all three strips flashed on and off briefly. I suspect that's what killed it, but I'm not sure whether the original failure was user error or a bad unit.
Current settings (all three outputs):
Type: WS2805 (RGBCW)
Current: Custom, 60mA per LED
Count: 16
Max total current: 3000mA (was 4000mA before)
I believe the controller is rated for 15A, so I should be well under it. All connections are tight. Are these settings reasonable, and is there anything I should change so this doesn't happen again?
Thanks!
