RFL 9550 Line Trap

The RFL 9550 Line Trap features low loss and modular design. RFL is able to design line traps according to customer requirements given the various application parameters such as outline dimensions and short time current per IEC Series-2 Standards. Check out the product brochure, it provides of all the information necessary to meet your product requirements.

RFL 9510 and 9510P Fixed Extra Wide Band Line Tuners

The RFL 9510/9510P Extra Wide Band Line Tuner matches the impedance of the powerline carrier (PLC) terminal to that of the high voltage power line in order to reduce the insertion loss for the transmission of PLC signals over the power line. In addition, isolation from the power frequency voltage and transient overvoltages is provided.

The RFL 9510/9510P series high-pass or band-pass line tuners filters are enclosed in casings made of fine-quality aluminum that can perform under all-weather conditions. Capacitors are of the highest voltage type. Inductor and matching transformer units are molded and sealed. A zinc-oxide lightening arrester is used as the protective device.

Model 9510 is used for phase-to-groud coupling, while model 9510P is used for phase-to-phase coupling.

RFL 9511 Adjustable Wide Band Line Tuner for Powerline Carrier Systems

The RFL 9511 Wide Band Line Tuner is used for coupling Power-Line Carrier (PLC) equipment to a single phase of high-voltage power lines, carrying out the following:

• Tuning of coupling capacitor to minimize the coupling impedance.

• Impedance matching between power line and communication equipment.

• Draining to ground of power frequency current, limitation of voltage surges coming from the power line and grounding of the coupling device for protection purposes.

The units can be used for phase-to-ground, phase-to-phase or three phase coupling. One RFL 9511 unit is used for phase -to-ground coupling. Two RFL 9511 units are required for phase-to-phase coupling with the two units being connected together through a differential transformer acting as a hybrid circuit. Three RFL 9511 units and two hybrid circuits are needed for three-phase coupling.
