Sendyne Module First to Precisely Measure DC Current & Voltage w/ typical accuracy of ??0.05 % measurement; measures temperature at 4 points
New York NY, USA3 ??? Sendyne has introduced the SFP100EVB, a turnkey module for precision measurement of current, voltage and temperature. Operating in the automotive temperature range of -40 ??C to +125 ??C, the module simultaneously measures bi-directional DC current through a 100 micro-Ohm resistive shunt, voltage and temperature at 4 points.
The module is capable of resolving currents from 3 mA to 513 A within a single continuous measurement range (without sub-ranging or gain switching), with uniform resolution of 61 ??A, and performs automatic charge accumulation for built-in precision Coulomb counting.
The module was created for applications where accurate current measurements under conditions of widely-changing temperature are essential, such as battery monitoring for industrial, automotive, grid and off-grid storage, as well as photovoltaic arrays, drive controls, and precision current flow measurements (including battery cells characterizations).
The SFP100EVB implements several of Sendyne???s patented and patent pending technologies in order to achieve precision current measurements for field use comparable to the precision of metrology grade lab instruments.
From +10 ??C to +50 ??C, the module typically achieves an accuracy of ??0.05 % for both current and voltage measurements. At the extremes of the full operating temperature range, the module achieves an accuracy of ?? 0.4 % for current measurement and ?? 0.6 % for voltage measurement.
Accuracy is defined as the cumulative effect of all possible sources of error, including offset, gain and stability of the built-in precision voltage reference.
The precision of the accumulated charge quantity in the Coulomb count register is higher than would be possible by reading and accumulating individual current measurements, due to a precisely uniform sampling rate and absence of jitter.
Moreover, if full-scale (positive or negative) current measurements are accumulated continuously, the Coulomb count register is capable of collecting up-to 43 years of data without over- or under-flow.
The module utilizes Sendyne???s SFP100 measurement IC that contains two 24-bit ?? ADCs.
Galvanic isolation allows both low-side and high-side current measurements and provides improved attenuation of system-induced noise.
Power consumption is typically 82 mW.
A complete evaluation kit for SFP100EVB is available that includes the module, a Serial-to-USB cable, as well as Windows???-based control software.
The software provides visual indication of all measured values, both in digital-meter and real time chart formats, as well as automatic saving of all data in files (data logging), with unlimited duration, for off-line review and export in an ASCII format.
Furthermore, it allows assessment and control of all internal registers and settings for the SFP100 IC utilized by the module.
Evaluation kits can be purchased directly from Sendyne.
