4K SDI Galvanic video isolator

Model No. : L4KGI 01


The L4KGI 01 is a galvanic signal and gound path isolator for use with 4K and 12G SDI video signals.  They are built in cylindrical “barrel” style enclosures and fitted with a BNC connector at each end and isolate both the signal and ground paths.

Also available in panel mount version with flanges, part number L4KGI 02


Bandwith:   0.5 MHz to 12.0 GHz
DC Breakdown voltage:    100 volts minimum
Input and output impedance:  75 ohms
Return loss:   >15 dB
Dimensions: 30 x 20 (l x diameter) mm
Weight: 36g


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.
