SGL-2

Ground Loop Isolator

SGL-2 is a ground isolator designed for coaxial cable video transmission equipment. It is built in a unique video isolation transformers and passive isolation circuit. Using magnetic circuit to connect the two devices can effectively cut off the loop current No power supply required, built-in transient protection, directly connect to camera or DVR, CCTV Monitor, etc.

Fitur SCP-005

Ground loop interference SGL-2 is common in CCTV system and difficult to resolve. It mainly refers to the 50 Hz frequency power interference. This kind of interference often causes roll black bar on image, so images are out-of-step and can not be watched. The main reason for ground loop interference is the potential difference. The distance between camera and control equipments is too long, grounding method is wrong or not complete, or load is not balance, etc.

All these reasons may lead to potential difference. If the cables are grounded at both ends, there will be a large current generated in the loop, which superimposes on video signals and cause interference. SGL-2 is a ground isolator designed for coaxial cable video transmission equipment. It is built in a unique video isolation transformers and passive isolation circuit. Using magnetic circuit to connect the two devices can effectively cut off the loop current No power supply required, built-in transient protection, directly connect to camera or DVR, CCTV Monitor, etc.
