ASP

Coaxial surge protectors against atmospheric discharges from the family ASP are intended for protection of radio stations and other equipment against indirect lightning and other discharging influences. The elements are usable within frequency range from 0 (DC) to 1500 MHz. They are composed of metal galvanically coated housing with two coaxial connectors. A special gas filled surge arrester is inserted in with the function of voltage-dependent switch. As soon as the voltage applied to the arrester exceeds the spark-over voltage, an arc is formed in the hermetically sealed region within nanoseconds. After that the arrester is capable to do his function further again.

ASP-.../W

Coaxial surge protectors against atmospheric discharges type ASP-W and ASP-WH are intended for protection of radio stations and other equipment against indirect lightning and other discharging influences. Compared with the model ASP, the ASP-W is designed as waterproof coaxial feedthrough and intended to be mounted on properly grounded panel mount plate.
The element is usable within frequency range from 0 (DC) to 1500 MHz (ASP-W) or from 1500 to 2500 (ASP-WH). The model ASP-W is composed of metal nickel coated housing with two coaxial connectors (type N, BNC or TNC). A special gas filled surge arrester is inserted in with the function of voltage-dependent switch. As soon as the voltage applied to the arrester exceeds the spark-over voltage, an arc is formed in the hermetically sealed region within nanoseconds. After that the arrester is capable to do its function further again. The model ASP-WH has protection enabled with short-circuited 1/4 wave stub.
