JLX,JLX series combined filterDetailed product description：

JLX, JLX series combined with filters are used in power line carrier channels, connected in series between the low voltage end of the coupling capacitor and the communication terminal, and together with the coupling capacitor, achieve the transmission of carrier signals and the isolation of power frequency currents. The JLX and JLX series combined filters are suitable for carrier communication channels and can cancel out the 0-200pF stray capacitance of the low voltage end of the coupling capacitor to ground. For relay protection channels, connect a 5000pF DC blocking capacitor in series at the output end of the cable side; Used for carrier channels, the cable output is directly output by a transformer.
The product adopts the standards of IEC481-1974 and GB7329-2008. The peak envelope power of the whole machine is 400W, 600W, 800W, and 1000W, suitable for 10 to 500 kV power line carrier systems.

The JLX, JLX series combined with filter models are as follows
JL-400-3.3/3.5/5.0/6.6/7.5/10/15/20-N3
JL-600-3.3/3.5/5.0/6.6/7.5/10/15/20-N3
JL-800-3.3/3.5/5.0/6.6/7.5/10/15/20-N3
JL-1000-3.3/3.5/5.0/6.6/7.5/10/15/20-N3
JL-1200-3.3/3.5/5.0/6.6/7.5/10/15/20-N3
