4K/12G SDI VIDEO Galvanic isolator (barrel style)


Product : 4K/12G SDI VIDEO Galvanic isolator (barrel style)

4K/12G Galvanic Isolator

Model No. : L4KGI 01


L4KGI 01 is a miniature inline isolator providing full broadcast quality transmission of the 12G/4K UHD SDI video signal whilst blocking both the signal and ground DC paths. 

It is for use with full 12G/4K UHD SDI video and all lower standards including 6G, 3G, HD and SDI.  It is built in a cylindrical plastic (for isolation) enclosure, fitted with a BNC connector at each end.  A version with industry/standard size flange mounting is also available, see Model L4KGI 02.

Transparent to a broadcast/quality signal, they are useful in both permanent and temporary installations.


  • Full DC galvanic isolation between equipment, both signal and ground path.
  • Protects equipment from damage by DC static and earth loop voltage built up.
  • No distortion of full 12G/4K UHD SDI broadcast quality signal
  • Can be used with all lower SDI standards including 6G, 3G, HD and SD SDI.
  • Small and lightweight.


Further Notes

Our LEN ground isolators use broadband high-pass filters to provide isolation of DC currents between two pieces of equipment, whilst permitting the full bandwidth of the SDI signal to pass, thus avoiding problems of signal distortion and operator shocks caused by a voltage difference. This method out-performs broadband transformers for SDI signals. Both signal and ground paths between equipment are isolated, there is no distortion of the signal. They are also suitable for ASI format.
