    • LEN LHDF03 HD-SDI Video Ground Isolator 4000 Volt - 4kV Breakdown

      LEN LHDF03 HD-SDI Video Ground Isolator 4000 Volt - 4kV Breakdown

      The LEN LHDF03 is suitable for SD or HD SDI signals. These have a higher breakdown voltage as required for medical applications. They are built into Insulating ABS boxes with mounting flanges, fitted with two female BNC connectors.

      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 pr

        • LEN LVIT02 Video Isolation Transformer - Analogue - 4kV Breakdown

          LEN LVIT02 Video Isolation Transformer - Analogue - 4kV Breakdown

          The LEN Video Isolation Transformer acts as BOTH a Hum Eliminator AND a Ground Isolator whilst also improving on the performance of the traditional individual products.

          The LVIT02 will remove severe interference caused by 50 or 60 Hz hum whilst a normal "Humbucker" will only remove moderate interference.

          At the same time it acts as a high performance Ground Isolator eliminating ground potential differences between equipment with a minimal phase and gain distortion. The LVIT02 has been developed to

                  Hum on video is caused by a multitude of reasons, all of which are common throughout the world. Hum in general is induced by four distinct causes: 1) ground loop caused by difference in ground potential, 2) electrostatic coupling, 3) magnetic coupling and/or 4) faulty circuit elements causing leakage. Hums caused by ground loops can be as large as several hundred volts & can be dangerous to a TV crew preparing the site.Common mode hum caused by differences in ground potential is often found in

                  Jensen VBH-5BB Component Video & VGA Hum Eliminator Ground Loop Isolator

                  The ISO-MAX VBH-5BB reduces ground current induced video interference such as "hum bars" by a factor of over 100, eliminating the visible effects of these types of interference. The high bandwidth and low VSWR prevent degradation of the picture quality due to high frequency roll-off and cable reflections.

                  When used with a D15HDM-5BF-3 VGA breakout cable, this is a great solution to eliminate hum from any VGA system.

                  • Provides 56dB Reduction in Ground Loops

                                        A typical High Definition Broadcast chain features potential interconnects that could result in ground loops and the introduction of induced noise. Even though SDI is more immune to extraneous noise and low frequency components (hum) problems can still exist. As with analog signals, once you have noise in the signal, it is extremely difficult and costly to remove. Jitter caused by induced noise effects can compound problems created by unstable signal sources, poor re-clocking systems, cable atte

Normal voltage differences between system grounding points cause small AC power currents to flow through video cables and even a small voltage drop can cause a visible hum bar. The low and high-frequency response of most video hum eliminatorsmake them ideal for high-definition and projection systems. Make sure you are stocked with plenty video hum eliminators for your next event.
