4.2 VS1_ADC and VS2_ADC Voltage Dividers

SM (TP6) will be the voltage divider measurement. The voltage measured is dependent on parallel resistors R1 and R2, and the resistor network R3-R9 or R10-R18. It can be calculated by the following equation:

Equation 1. V S1_ADC = R 1 | | R 2 ( R 3 + R 4 . . . + R 9 ) + ( R 1 | | R 2 ) × V L O A D
Equation 2. V S2_ADC = R 1 | | R 2 ( R 10 + R 12 + R 13 + R 14 + R 15 + R 17 + R 18 ) + ( R 1 | | R 2 ) × V L O A D
