2. Voltage
Current across CAT-6 Cable: 2.9A (max)
Inverter Voltage: 60V
Current x Resistance = Voltage Drop
Example:
2.9A x 3Ω = 9V
Inverter Voltage
– Voltage Drop = Voltage on Inverter
Example:
60V
– 9V = 51V
3. Power
Voltage on Inverter x Current = Power to Receiver
Example:
51V x 2.9A = 148W
Power to Receiver - Power Used by Receiver = Available Power
Example:
148W
– 10W = 138W
Available Surge Power Calculations (Example Calculations for 300ft Cable)
1. Voltage
Surge Current: 4.5 A
Surge Current x Resistance = Surge Voltage Drop
Example:
4.5A x 3Ω = 14V
Inverter Voltage
– Surge Voltage Drop = Surge Voltage on Inverter
Example:
60V
– 14V = 46V
2. Power
Surge Voltage x Surge Current = Surge Power
Example:
46V x 4.5A = 207W
Surge Power to Receiver
– Power Used by Receiver = Available Surge Power
Example:
207W
– 10W = 197W
