Smart Meters

Enabling robust AC/DC power supplies through PrimAccurate™ technology

Dialog's AccuSwitch™ and PrimAccurate™ technologies enable robust power supplies for Smart Meters that meet stringent global efficiency and no-load stand-by power consumption standards while offering a low BOM cost.

Digital power conversion up to 45W

Dialog’s PrimAccurate™ AC/DC converters and controllers are rugged and reliable, offering near-zero stand-by power consumption, efficiency greater than 85% and a high level of integration removing fragile opto-isolators and Y-caps. This technology uses proprietary digital algorithms that perform real-time waveform analysis to monitor the output voltage and current through an auxiliary winding on the main transformer instead of using direct feedback from the output voltage (isolated or non-isolated). Cycle-by-cycle analysis through Dialog's digital technology allows for tight load and line regulation to input and output changes and full protection without costly additional components such as power sense resistors.
