5VDC BNC Surge Arrester / CCTV Surge Protection Device with10kA
20KA
OBVT-BNC
Coaxial BNC Video Surge Protectors are designed to guard computer
network system that includes the monitoring system of security
system, coaxial signal transmission and close -circuit TV,
satellite communication system.
OBVT is the series of devices for discharging transient
overvoltages induced in coaxial lines. In accordance with IEC
61643-21. Coaxial format.
Suitable for the protection of radiofrequency transmission and
reception equipment. By their nature, they are highly exposed to
induced transient overvoltages (surges) associated with
meteorological activity.
For BNC, F, N, TNC connectors.
Ideal for the protection of transmission and reception systems such
as TV and radio antennas, closed circuit TV (CCTV), alarms, etc.

Note: The system lightning protection does not guarantee that the
equipment will not be 100% damaged by lightning; the power system
must be multi-level lightning protection;
The complete lightning protection system includes external
lightning protection and internal lightning protection. External
lightning protection refers to: lightning receptors, down
conductors, and grounding bodies, which are mainly used to defend
against direct lightning strikes. Internal lightning protection
includes: shielding, reasonable wiring, safe distance,
equipotential connection, overvoltage protection, etc., mainly used
to prevent lightning induction, ground potential counterattack,
lightning wave intrusion, etc.
Application
●AC/DC distribution
●Power supplies
●Industrial automation
●Telecommunications
●Motor controls systems
●PLC applications
●Power transfer equipment
●HVAC applications
● AC drives
●UPS systems
●Security systems
●IT/Data centers
Tip: 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.

Importance of theground connection
Overvoltage protectors (SPD) divert excess energy toground, so
limiting the peak voltage to an acceptablevalue for connected
electrical equipment.
A ground connection in adequate condition is, therefore,a key
aspect for effective protection against overvoltages.Monitoring
ground connection condition guaranteesproper operation of surge
protection devices.
What skills should lightning protectors have in the selection?
1.Confirm power supply system
First of all, you must determine what your power distribution
system is like, whether it is TT, TN or IT system. After
determining the power distribution system, you can choose the
protection mode and wiring method of the lightning arrester to
select the appropriate lightning arrester.
For example, TN-C uses 3P lightning protection device, TN-S uses
4P, TT uses 3P+N, etc.
2.Know the main parameters of the lightning arrester.
