Protects 24V Power, Video Signals & Data ? Designed for the complete protection (common & differential modes) of the latest PTZ (pan, tilt and zoom) cameras. Protects 24VAC power, local data circuits and ultra sensitive video signal circuits. Utilizing 5 stage multi-component design (Sidactors, Tranzorbs, MOV’s, resistors and self-resetting “SmartFuses” ) for fast response to high exposure environments. Clamps at 6.0 volts (center pin to shield) and built into durable weatherproof enclosure. Protects both differential and common modes. 3V signal clamp available by request, add suffix “LC”.
