CCTV Surge Arrester Protection Device for combination video signal
and AC power
CCTV Surge Protector
CCTV surge protector is a single channel, in-line, coaxial
multi-stage video surge protector for analog cameras or head-end
applications. CCTV camera surge protector is designed to provide
multi-stage surge protection for one channel of video. The unit has
MNC type connectors at the input and output for connection to the
coax and is ideally suited for small or restricted spaces where a
single line of video needs to be protected. CCTV Surge Protector
provides power to the camera with the same unit.

Installation and Maintenance
1. Fix the surge protective device on the wall or place the plane,
connect the wire according to drawing.
2. PE connect with the earthing, Earth resistance should accord
with the standard of lightning protection.
3. The distance should be within 1 meter between being protection
device and surge protective device.
4. Surge protective device will damaged and signal interrupter when
maximum continuous operating voltage overrun.
5. When its maximum continuous operating voltage overrun, surge
protective device will damaged, if happened, please
remove surge arrester immediately and choose suited surge
protective device.
Note: Lightning protection is probabilistic protection, and we
cannot provide 100% protection.
First, lightning discharge itself has a certain degree of
randomness, and lightning parameters have certain statistical
properties, which determines that all protective measures based on
these statistical characteristics of lightning parameters cannot
provide 100% protection. Such as: direct lightning
protection-shielding characteristics; lightning current amplitude,
waveform, etc. have statistical properties;
Second, the lightning protection equipment cannot prevent the
formation of lightning flashes;
Third, lightning protection devices cannot ideally eliminate all
interference voltages/currents. The fundamental purpose of taking
protective measures is to ensure that most of the energy caused by
interference does not spread to the vulnerable parts of the device
and the staff.
Finally, the cost of protection against high-level surges with a
small probability of occurrence has risen sharply.

Tip: How can I distinguish the quality of the lightning arrester?
1. It can be seen from the reaction time: determine whether the
lightning arrester can respond in time and quickly discharge the
lightning current.
2. It can be seen from the insertion loss: this refers to the
installation of a lightning protector, the impact of this lightning
protector on the line, the smaller the better
3. It can be seen from the number of impact resistance: determines
the service life of the lightning arrester. Generally, the gas
discharge tube will not drop after being placed for a period of
time. If you want to check its quality, you can use an adjustable
high-voltage DC power supply to test .
*The main parameters of the lightning arrester
(1) Nominal voltage Un: The additional voltage of the maintained
system is consistent with it. In the information technology system,
this parameter indicates the type of maintainer that should be
selected, and it indicates the effective value of the communication
or DC voltage.
(2 Maximum continuous voltage Uc: The maximum effective voltage
value that can be permanently applied to the designated end of the
lightning protector without causing changes in the characteristics
of the lightning protector.
(3) Nominal discharge current In: The lightning protection device
is not damaged by applying a standard lightning wave with a
waveform of 8/20μs to the lightning protection device for 10 times.
(4) Maximum discharge current Imax: The peak value of the maximum
impulse current that the lightning protector can withstand when a
standard lightning wave with a waveform of 8/20μs is applied to the
lightning protector for one impact.
(5) Voltage protection level Up: The voltage protection level of
the lightning arrester in the case of In.
When selecting the type, the Uc of the lightning arrester must meet
the system voltage, the flow rate must meet the use requirements,
and the protection level must be lower than the equipment withstand
voltage.
