LEN LHDF03 - HD-SDI 4kV Ground isolator

LEN 3G, HD-SDI Ground Isolator uses a broadband highpass filter to provide DC electrical isolation between the two pieces of equipment, whilst permitting the full bandwidth of the 3G-SDI signal to pass. This method outperforms all other broadband transformers for SDI signals currently available. Also known as the 3G-SDI DC Isolation Highpass Filter, it is non-inverting and suitable for ASI format.

Traditional “Humbucker” and Isolation Transformer approaches to interference are not applicable to SDI signals. Mains hum is well below the SDI signal frequency spectrum and (unlike analogue video) the SDI signal is not sensitive to near-DC attenuation. However, the problems of signal distortion and operator shocks caused by a voltage difference between two pieces of equipment connected by a HD-SDI signal feed still exist.
