Diamond SP3000P surge protector N plug 400W 0-3000MHz

The Diamond SP3000P surge arrester operates for frequencies from 0 to 3000 MHz and for a maximum transmission power of 400W, it is equipped with an N plug connector and offers a low insertion loss of -0.3 dB.

This equipment provides protection for the radio equipment in the event of a nearby lightning strike , but not in the event of a direct lightning strike on the antenna, in this case it is necessary to install a lightning rod above the level of the lightning. 'antenna.

The SP3000P must be grounded , by the shortest route, for safe operation. A stainless screw (M4) is available to connect a cable to earth.

It is recommended to place a surge arrester both at the level of the antenna, as well as at the level of the entry of the coaxial cable in the building.

The SP3000-P is not waterproof and must be protected for outdoor use.

Recommendation for the use of the lightning arrester:

  1. Do not share the earth line with other earth lines such as power lines. It is recommended to separate the earth line of the surge arrester from those of other systems
  2. Although the hardware is designed to protect radio equipment from high surges caused by lightning or static electricity, it cannot protect the equipment from high current and voltage caused by direct thunder clap on the antenna. . To protect the equipment from direct lightning strike, install a suitable lightning conductor separately
  3. To achieve maximum safety, the equipment uses an integrated pressurized gas tube surge arrester element to discharge and ground the electric current when it exceeds the predetermined discharge voltage.
