LMU impedance matching device

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.
