USER_ADC_FULL_SCALE_CURRENT_A ??????????????

[karu2003]

Hello,

How did you find this #define USER_ADC_FULL_SCALE_CURRENT_A (69.7)?

3,3 / 69,7 = 0,04734V/А. ??????????????????

You have a divider 22/(22+10) = 0,6875

You have ACS724LLCTR-30AB-T - 0,066V/A 0,066V/A * 0,6875 = 0,04537V/A

30А * 0,066V/А = 1,98V 1,98V * 0,6875 = 1,36V

Imax = 1,36V / 0,04537V/A = 29,97A Ifull = 59,95A
or
Imax = 1,65V / 0,04537V/A = 36,36A Ifull = 72,73A
