1Power Protection and Conditioning
The STC-CCTV Series is tailored specically to CCTV, data,
audio and cable applications. These units are single Coax
Surge Protective Devices implementing three-stage hybrid
technology. They address overvoltage transients with
a primary gas tube, and secondary silicon avalanche
components. Over-currents (e.g. sneak and fault currents)
are mitigated with solid-state resetable fuses (PTCs). The
STC-CCTV units are designed in accordance with NFPA
780 (2004 Edition) requirements, with up to 20kA of surge
current capability. The STC-CCTV-75I model has an isolated
ground and is recommended for use at the camera end.
