LEN Digital Video Galvanic Isolators

LEN Digital Video Galvanic Isolators

L E N ground isolators use broadband high-pass filters to provide complete galvanic 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 AES/MADI/ASI format.

Three versions are stocked; an in-line 'barrel', an in-line 'barrel' with a mounting flange, the third offers designs with higher breakdown voltage for medical grade applications.

The 4K product is for use with full 12G/4K UHD SDI video and all lower standards including 6G, 3G, HD and SD SDI. The 3G product is for use with 3G SDI video and all lower standards including HD and SD SDI. The HD product is for use with HD SDI and SD SDI video.

Dimensions:

(in-line) 30 x 20 (length x diameter) mm. Weight: 36g.
(with mounting flange) 30 x 20 (length x diameter) mm, mounting flange 31 x 26 mm. Weight: 37g.

Optional accessories:

The LEN-MPG01 rack frame is a 1U 19-inch full width panel, finished in black, punched to take sixteen Isolators mounted from the rear by means of the mounting flanges, so that the BNC connectors are on either side of the rack. The LEN-MPG02 rack frame is a 1U 19-inch panel, punched to take eight Isolators, mounted in the same way as the full width panel.
