Shunt size and sense power

Example shunt bound

Rmax uses the entered Vout, gain, and Imax. No nearest commercial value is chosen.

Worked example

R

Shunt size

0.00132 ohm

Power

2.5 W

Sense voltage 0.05 V

V_sense = Imax * R_shunt

Rmax <= Vout_max / (Gain * Imax)

P = Irms^2 * R_shunt

Error analysis

Minimum current is omitted because offset or error factor is blank. Enter both, or leave them blank to skip this result. An entered 0 is a real zero, not a blank.

Resistance shift is omitted because nominal resistance, TCR, or temperature change is blank. Enter all three. An entered 0 is a real zero.

Resistance and voltage use the units you select and are converted before the formulas. The error factor is not divided by 100. No amplifier part is selected. A 2x wattage margin is not applied.
