Product Overview

The STEVAL-XPLM01CPL from STMicroelectronics is a power line communication AC coupling circuit. It includes simple two-wire connectivity to any PLC transmitter/receiver and a standard connector for an AC power cord (2-pin AC plug, 8-shape female end). The main components to achieve suitable signal coupling are PLC 1:1 transformer for differential coupling and basic electrical isolation, SM6T15CA 600W Transil +320VAC varistor for effective protection against ESD, EFT and surge disturbances from the power line, high voltage AC blocking capacitor with X2 safety class and tuning series inductor to adjust the frequency response. The STEVAL-XPLM01CPL can be very easily interfaced with the X-NUCLEO-PLM01A1 to test PLC communication performance over an AC mains network. The frequency response of the coupling circuit is wide enough to fit any narrow-band PLC signal under normal test conditions. However, it can be easily adjusted by changing only the tuning series inductor L1.
  • Complete AC coupling circuit suitable for use with any power line communication (PLC) solution
  • Can be paired with the X-NUCLEO-PLM01A1 to add full AC coupling capability
  • Tuned for transmission inside CENELEC B to D bands
  • Implements isolation and protections for safe operation
  • Suitable for the connection of laboratory equipment for PLC measurement and testing


Power Management


Market demand for this product has caused an extension in leadtimes. Delivery dates may fluctuate. Product exempt from discounts.


STEVAL-XPLM01CPL must be used by expert technicians only. Due to high voltage (85VAC to 265VAC)present on non-isolated parts, special care must be taken in order to avoid electric risks for safety.
