STEVAL-IPE009V1 Mono-Phase / Multi-Tariff Energy Meter based on ST72321B and STPM14

This demonstration board is an integrated system designed to provide the user with a complete, ready-to-use energy meter application. It is a medium-end solution for power metering, using the ST72F321BR9T6 microcontroller, the M41T94 RTC (real-time clock), the M95256 EEPROM and the STPM14 energy meter ASSP device.

The multi-tariff energy meter demonstration board implements many features that can be used as a starting platform for evaluation and development of meter applications, including multi-tariff management, absolute and average maximum demand calculation, two types of tamper management, and power failure management.

技术特性
  • Cost-effective and flexible
  • Meets Class 1 accuracy for IB = 5 A and Imax = 80 A according to IEC 61036:1996 + A1: 2000 - Static meter for active energy (classes 1 and 2)
  • Operating voltage range 220 V ± 20%
  • Continuously detects and displays no-load conditions, reverse direction, fraud and case tamper conditions
  • Configurable number of tariffs (1 to 4) and maximum demand type (day, one month or three month)
  • Accumulated data for whole meter life (total kWh consumption, average MD (maximum demand), total number of tariffs, tariff time slots, consumption under different tariff rates, power failure date/time)
  • Data for last 12 months (consumption under tamper mode for each month, first/last case/fraud tamper date/time, total tamper time and power failure accumulating time for each month)
  • Data for absolute maximum demand (absolute MD, date/time) according to type of MD requested
  • SW LCD driver for 24 x 4 segment LCD glass with contrast control
  • RTC with SPI for real date/time
  • EEPROM with SPI for storing 256 Kb of data
  • Case tamper detection even in power-down
  • External switch for viewing all data stored in EEPROM sequentially even when AC power is not available
  • Battery backup to detect tampering and see all parameters stored in EEPROM even during power-down
  • Single point and fast calibration of the STPM14 for Class 1 meter
