The EVALSTPM34 evaluation board is a class 0.2, dual-phase meter with 2 CTs for power line systems with Vnom = 140 to 300 V(RMS), Inom / Imax = 5/100 A(RMS), flin = 50/60 Hz ± 10% and Tamb = -40 to +85 °C. Measured active/reactive power can be output from two programmable LEDs on the board. The board can be interfaced with a PC running evaluation software through an isolated USB-to-UART port, or through the STEVAL-IPE023V1 USB (SPI) isolated interface tool for configuration and data reading. The board also has SPI/UART pins available to interface a microcontroller for application development. https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2017-03-26 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2017-09-09 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2020-06-05 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2021-04-02 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2021-07-15 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2021-12-03 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2022-03-16 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2022-04-10 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2022-06-11 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2022-06-24 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2022-10-08 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2024-08-01 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2024-08-27 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2024-09-05 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2024-09-22 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2025-06-27 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2026-03-21 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2026-06-04 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2026-07-23 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2026-08-30 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2026-10-09 https://elecena.pl/product/8157180/evalstpm34-dual-phase-energy-metering-evaluation-board-with-2-current-transformers-based-on-the-stpm34 2026-10-19
