Azco Ground Loop Isolator With Built in TVS
- Product Information
This Ground Loop Isolator is designed to solve electrical differences in the ground from two different areas. These differences are often seen as a roll in the picture or a thick black bar. The unit has built in TVS. Grounding issues are common to many sites, and can leave installers thinking that they have faulty equipment. A ground loop occurs where an unintended connection to ground is made through an interfering electrical conductor. Generally, this occurs when an electrical system is connected to the electrical ground in more than one way such as when two or more devices are connected to a common ground through different paths. When this occurs on CCTV, it causes rolling lines through the picture, fuzz, black bars etc. This problem is common when mounting cameras to metal buildings. The same picture problems can be caused by low voltage cables being run by other electrical cables. A Ground Loop Isolator can be used to solve these problems quickly. The unit has a BNC male to BNC female with a 25cm mini cable on both sides. It is passive, requiring no power. The unit prevents video-signal distortion caused by video ground loops, eliminating picture tearing, cross talk and rolling and also prevents power cables laid by others from interfering with the CCTV system. It has built in TVS for surge protection. Insertion Loss of 0.5cB; Frequency Response of 0-3dB at 10Mhz; Input and Output Resistance of 75 ohm each; Isolation Voltage of 600VDC minimum; Insulation Resistance of 100m Ohm.
