Application
LFP-912 is an amplitude-modulated power line carrier (PLC) transmitter /receiver. The LFP-912 is designed for directional comparison blocking applications with high-speed protective communications. The operating frequency can be configured by mini-switches or jumpers. The frequency can be set from 40 kHz to 400kHz, in 4kHz steps.
Features
l By using new frequency and sine wave synthesis technique，the transmitter could produce sine wave carrier signal directly without a preamplifier and filter for transferring square wave to sine wave.
l Frequency band is shifted upward in demodulation. A high-Q fixed frequency filter up to 1MHz is equipped with. It is not needed to change high frequency receiving filter according to the frequency used.
l The frequency could be changed easily on the site. Besides the small digital switches on the transmitter module，the jumpers on the filter module can also set the frequency.
l Redundancy of the receiving level is very high. In the range of + 6 dB to + 18 dB，the redundancy value could be displayed directly via LED.
