STPM01 - effective measurement of active, reactive and apparent energy.

The STPM01 is designed for effective measurement of active, reactive and apparent energy in a power line system using Rogowski coil, current transformer and shunt sensors. This device can be implemented as a single chip monophase energy meter or as a peripheral measurement in a microcontroller based monophase or 3-phase energy meter.

Features:

Active, reactive, apparent energies and RMS values Ripple free active energy pulsed output Live and neutral monitoring for tamper detection Easy and fast digital calibration in only one point over the whole current range OTP for calibration and configuration Integrated linear VREGs for digital and analog supply Selectable RC or crystal oscillator Support 50 ÷ 60 Hz - IEC62052-11, IEC62053 - 2x specification Less than 0.1% error Precision voltage reference: 1.23 V and 30 ppm/C max
