Columbia Weather Systems, Inc. 

Surge/Lightning Protectors 

 

A nearby lightning strike may induce a high voltage surge which the 
internal suppressor of your weather instrument may not be able to 
withstand, causing significant damage to the weather station. Protect 
your weather station investment with the Orion Surge Protector. This 
compact transient overvoltage suppressor is designed for weather 
stations in areas with an elevated risk of lightning strikes such as the top 
of high buildings, or installations with cable lengths greater than 100 feet. 

 

Superior 3-stage surge protection 

 

Tolerates up to 10kA surge currents 

 

Both differential and common mode protection on each channel 

 

Filtering against HF and RF noise 

 

Two power channels and two data channels 

 

Environmental protection class IP66 

Catalog Number: 8355 
Includes adjustable mounting kit
