Surge protection for video ­surveillance systems

June 2013 Electrical Power & Protection

Copa’s new COP903 is a surge protection device for coaxial cable-connected systems such as video surveillance systems and similar equipment. This unit also protects the 12 VDC voltage supplied from the power supply to the cameras. The SPD is DIN rail mountable which makes for a neat installation into 19’’ racking systems.

With a nominal operating voltage of 5 VDC, COP903 has a BNC (F)-Line or a BNC (M)-Equipment connecting terminal. Video signal cables are plugged into the surge arrester with the equipment plugged into the protected side.

Suitable for a wide range of signal frequencies, the surge arrester has a quick response time and a low 0,5 dB insertion loss. It has a maximum discharge current of 10 kA and voltage protection up to 150 V.

The green LED alarm mode indicates normal operation, while a ‘light-off’ indicates a failure condition. The cost-effective surge protection device operates in a temperature range from -40 to 70°C.
