Sendyne’s new current measurement module

Sendyne SFP102 Module

Sendyne’s new SFP102MOD is a shunt-based enclosed module capable of current measurements to 375 A, with 45 µA resolution. The company’s patented Continuous Calibration technology enables ±0.25% accuracy for any current magnitude, within the operating temperature range of -40 °C to +125 °C.

The new module is designed for situations that require accurate current measurements under widely-changing temperature conditions, such as battery monitoring for automotive and stationary storage applications.

The SFP102MOD features built-in precision Coulomb counting (charge accumulation), with separate counters for charge, discharge and total Coulombs, enabling accurate State of Charge estimation. The supply voltage range is +3.3 V to +12 V. Power consumption with a 3.3 V supply is under 30 mW.

For customers requiring even greater accuracy, Sendyne offers individually calibrated units that achieve 0.05% accuracy up to 50 A, and 0.1% accuracy up to 200 A.
