STEVAL-IPE015V1 STMicroelectronics

STEVAL-IPE015V1 Single-phase energy metering demonstration board with two current transformers based on the STPM10 Data brief Features Single-phase, class 0.5 accuracy V (RMS) = 140 to 300 V, I /I (RMS) = nom nom max 2/20 A, f = 45 to 65 Hz lin Tamper detection for power line systems Capacitive power supply SPI interface connector RoHS compliant Description The STEVAL-IPE015V1 demonstration board is a STEVAL-IPE015V1 class 0.5, single-phase microprocessor-based meter with tamper detection for power line systems of V = 140 to 300 V , nom RMS I / I = 2/20 A , f = 45 to 65 Hz and nom max RMS lin T = -40 to +85 C. amb A stepper motor display shows the values of the energy measured by the standalone meter. The tamper detection feature implements two current transformers which monitor the live and neutral wire currents. The STEVAL-IPE015V1 demonstration has a 10-pin connector to be interfaced to a microcontroller or to a PC through a parallel or serial programmer for reading data.
