The STEVAL-XPLM01CPL is a simple yet very useful tool for power line communication testing on AC power networks. 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 600 W Transil +320 V ac varistor for effective protection against ESD, EFT and surge disturbances from the power line - High voltage AC blocking capacitor with X2 safety class - 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. The STEVAL-XPLM01CPL is suitable for lab measurements using equipment like an isolated probe for an oscilloscope or a spectrum analyzer, or to inject a signal from an arbitrary function generator. https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2017-09-04 https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2017-09-10 https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2021-04-02 https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2022-06-11 https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2022-06-24 https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2023-03-26 https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2023-07-18 https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2023-12-07 https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2025-06-27 https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2026-03-11 https://elecena.pl/product/10167125/steval-xplm01cpl-power-line-communication-ac-coupling-circuit 2026-03-21
