Uc 8VDC CCTV Surge Protection Device , Aluminum Alloy BNC Surge Protector

Product Description

Uc 8VDC BNC CCTV Surge Protection Device Voltage protection level <120V

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.

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.

Others

Technology SPD parameter(Note:According to user requirement ,can be customized Uc=140V,440V,550V,voltage range of range of the SPD):

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.
