This document describes how to use the STPM01 metering device and a shunt current sensor in single-phase metering applications, while emphasizing the special considerations to be taken into account in shunt design.
This document explains how to use a shunt current sensor with the STPM01 metering device for single-phase metering applications that do not require tamper detection. It outlines special design considerations, such as maintaining constant current density and reducing power dissipation to prevent explosion hazards in the meter housing.
The note details the theory of operation regarding shunts, including issues like non-linear resistance, self-heating, and accuracy requirements for class 0.5 direct meters. It provides specific configuration settings (PST = 3, ADDG = 1) and discusses wiring practices to minimize electromagnetic interference.
The device should be configured with PST = 3 and ADDG = 1.
No, it is not possible because one would generate its output at a high voltage level.
