Load calculation example
For a 24 V LED strip with 12 W/m:
-
Load per channel calculation:
- 12 W / 24 V = 0.5 A for every meter of LED strip
- Maximum load per output is 4 A
- 4 A / 0.5 A/m = 8 meters is the maximum LED strip length per output
- Longer strips can be split and controlled with multiple outputs
- For RGB strips divide W/m by 3, for RGBW by 4
-
Total module load calculation:
- Total module load: 25 A
- For 24 V: 25 A × 24 V = 600 W
- 600 W / 12 W/m = 50 meters is the total maximum length of all strips
