High Discharge Current MOV Surge Protection Class II 3 For TV Antenna
|
AC 385VMOV Surge Protection ,Class II SPD With Protection Rating IP 20
The surge arrestors OBV1-C40 meet the type 2 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions. The use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current. If circumstances are uncertain and there is a risk of fire from an overload, the internal cut-off unit disconnects the arrestor from the mains if necessary. In addition, the QR code printed on the arrestor allows disary. In addition, the QR code printed on the arrestor allows direct access to the online installation instructions.
Feature:
1,Protect electric system and on-loading electrical apparatus from
thunder and instantaneous over-voltage.
Application:
• SPDs for CCTV is mainly used for supervisory control system,
preventing product from lightning strike and surge. • Protect the video equipment effectively and ensure the image can
display normally5.Inhibit the overvoltage pulse issue fromthe transmission line on the camera
effectively, Avoiding the video surveillance equipment damage due to overvoltage pulse. • Offer surge protection for almost any products application in
power, instrumentations and controls, network and data lines, coax and etc. • For Radio Antennas, GPS Antennas, CATV, CCTV and Satellite TV.
Advantage:
• Lower Prices • Low Capacitance • High Discharge Current • Continuous and repeated protection in intense environment
Technology SPD parameter(Note:According to user requirement ,can be customized Uc=140V,440V,550V,voltage range of range of the SPD):
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.
