Key features
  • Based on STM32L433VCT6 (100 pins, LQFP) and STPM33
  • STPM33 interfaced using SPI with MCU
  • Current transformer (CT) and shunt sensing supported for current measurements
  • Shunt connected on the primary channel and CT on the secondary
  • Active energy difference of two channels signaling tamper condition
  • Magnetic tamper detection using Hall effect sensor by MCU interrupt line
  • EEPROM interfaced using I²C with MCU to store accumulated energy
  • Switch interface for case tamper and terminal cover tamper
  • Low power mode supported
  • Neutral missing tamper detection implemented using special duty cycling algorithm
  • Connectors for GPRS or Sub 1-GHz connectivity
  • Measuring RMS/instantaneous voltage, current, kW and power factor (PF)
  • Glass LCD (1/8 duty cycle and 20 segments) driven by the MCU LCD controller
