Voltage at the strip and the power supply
How much voltage is lost in the cable from the supply to the strip, and how much actually reaches the strip.
From the strip datasheet, e.g. 4.8, 9.6, 14.4
Supply to strip, one way
Voltage at the strip
23.3 V
- Current
- 3 A
- Voltage drop
- 0.7 V
- Loss of the supply voltage
- 2.9 %
ΔU = 2·L·I·ρ / S, copper ρ = 0.0175 Ω·mm²/m. The drop inside the strip itself is not included — that is what the single-feed length is for.
