Coupling Device (LMU)
The 650W Coupling Device comprising of coupling filters and protective devices is used to couple the PLCC terminals onto the high voltage transmission line. The device is purely passive and is inserted between the low voltage terminals of the coupling capacitor and the co-axial connection to the carrier terminal. The coupling filter, together with the coupling capacitor forms T section band pass filter with multi band selections.
FEATURES
Programmable pass bands
Coupling Capacitor values programmable
Equipment side impedance programmable
Equipped with three element protection devices (Drain Coil, Earth Switch & Lightning arrestor).
Designed for outdoor usage and can be conveniently mounted on the CVT tower.
The equipments meet IP-55 specifications.
