Description
The STPM34 evaluation board is a class 0.2,
dual-phase meter with 2 CTs for power line
systems with V_nom = 140 to 300 V_(RMS),
I_nom / I_max = 5/100 A_(RMS), f_lin = 50/60 Hz ± 10%
and T_amb = -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 RS232
port, or through the STEVAL-IPE023V1 USB
isolated interface tool for configuration and data
reading.
The board also has SPI/UART pins available to
interface a microcontroller for application
development.
