DC Voltage Drop Calculator
Calculate the DC voltage drop at the terminals of equipment due to cable resistance given a nominal voltage supply and rated power.
Input Data:
Calculation output
The equations:
$$I_{load} = {Power \over SupplyVoltage}$$
$$Voltage Drop = Load Current * 2{Cable Resistance Per Km \over 1000} * CableLength$$
$$Terminal Voltage = Supply Voltage - Voltage Drop$$
$$Percentage Voltage Drop = {Voltage Drop \over Supply Voltage * 100}$$
