The device is specifically designed to provide all the necessary features to implement a single phase energy meter without any other active component.
The STPM1x family is designed for effective measurement of active energy in a power line system using Rogowski Coil, current transformer, and shunt sensors. The device integrates an analog part with preamplifiers and A/D converters, and a digital part with a DSP unit to compute consumed active energy.
Key features include ripple-free active energy pulsed output, direct stepper counter drivers, support for various sensor types (shunt, CT, Rogowski coil), and live/neutral monitoring for specific models. The IC supports 50 + 60 Hz specifications and offers less than 0.1% error.
| Operating ambient temperature range | -40 to 85 °C |
|---|---|
| Current on any pin | +/- 150 mA |
The device supports shunt, current transformer, and Rogowski coil sensors.
Calibration is done easily and fast at only one load point via digital configuration.
