The main task of this device is to match the impedance between the PLC telecommunication system and high voltage line equipment. The impedance matching action in LMU is done by a transformer which together with the coupling capacitor plays the role of a high pass filter. LMU coupling models can be used as phase to phase (inter-circuit) and phase to ground (single circuit). This product has type test from EPIL reference laboratory according to IEC481 standard and IP54 degree of protection.
