Description
The STPM33 energy metering evaluation board is
a class 0.2, single-phase meter which includes
tamper monitoring, CT and shunt current sensors
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 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.
