CF-140
Power Line Carrier Coupling Filter
Application:
The CF-140 Coupling filter is used in power line carrier channel, connected in series between the low-voltage side of coupling capacitor and PLC equipment. It works with coupling capacitor to form a band-pass filter, which accepts the PLC carrier frequency signals and rejects the power system frequency.
