Example with Vref = 0.5 V:
ââ The 8 A version has a measuring range from 0 A to 40 A
ââ The 15 A version has a measuring range from 0 A to 75 A
ââ The 25 A version has a measuring range from 0 A to 80 A at TA = 105° C
Example with Vref = 1.5 V:
ââ The 8 A version has a measuring range from - 10 A to 30 A
ââ The 15 A version has a measuring range from - 18.7 A to + 56.3 A
ââ The 25 A version has a measuring range from - 31.2 A to + 90 A at TA = 85° C
