PRC series (Quarter Wave Protection)

Quarter Wave DC Blocked Protection is an active band pass filter. It has no active components. Rather the body and corresponding stub are tuned to one quarter of the desired wave length. This allows only specific frequency bands to pass through the unit. Since lightning operates only on a very small spectrum, from a few hundred kHz to a few MHz, it and all other frequency’s are short-circuited to ground.

The filter may be selective (narrow band or wide-band), according to the calculation of various mechanical elements.

The PRC technology can be selected with very narrow band or wide band depending on the application. Surge current withstand is the depending on connector type. Typically, a 7/16 Din connector can handle 100kA 8/20μs while an N-type connector can handle up to 50kA 8/20μs.

AC/DC power injection is not possible with this technology typical application is the protection of radio lines that do not have a source voltage

The efficiency of coaxial protectors is highly dependent on proper installation, in particular their connection to the earthing network of the installation.
The following installations rules must be strictly observed to ensure the efficiency:

  • Equipotential bonding network: all the bonding conductors of the installation must be interconnected and connected to the installation earthing network.
  • Optimized connection of the protector to the bonding network: to reduce the residual voltages during lightning discharge currents, the connection of the protector to the bonding network must be as short as possible (less than 50 cm) and has a proper cross section (at least 4 mm²).

The «feedthrough mounting» versions perfectly meet all these requirements.
Warning: Carefully remove all paintings or insulating coatings to ensure good contact..

  • Location of the protectors: they should preferably be placed at the entrance of the installation (to limit the penetration of lightning currents) and also near sensitive equipment (to enhance protection).
