XS2410 - Current and Voltage Accuracy Clarification

adamrosy — Wed, 14 May 2025 10:19:28 GMT

I have a question regarding the stated current and voltage measurement accuracy for the XS2410.

Am I correct in understanding that the measurement accuracy increases with increasing current? Reading the graph, an output current of 50mA, I would expect the measurement to be within 30% of actual, and at 1A the accuracy would be within ~8% of actual?

I cannot find any information about the range values for the stated "low" and "high" current ranges so that would also be useful to know if the accuracy changes in either of these ranges, or if the graph can be used to determine the accuracy.

Thank you!

Hello Adam,

Yes, the current measurement accuracy does improve with increasing load current. At very low currents (e.g. 5mA), the error is high, so those measurements are useful mainly for detecting presence or absence (e.g. open load), not for precision. At mid-range current (e.g. 200mA), the error drops significantly, but is still not ideal for precise monitoring. Once you reach 1A or more, the current measurement is much more reliable and within ±6%.

BRs, Tomas
