Primary detecting element  
Pick up coil unit
    It is an exclusive primary detecting element for detecting the influence of the thunder serge which arises in a low-voltage cable. 
(130x85x50 (mm), however the projecting place are outside a size.) 
It is used for the main part of a thunder detector, connecting using 75 (Ω) coaxial cables. 
It is used in combination with SPD of UL/CE 
ClassT・Uor ClassT・U・V

Don't combine any SPD other than UL/CE SPD by any means.

Detection part
Popov Thinder  unit 
  It is the compact main part of a thunder detector which contained coherer. 
(mm), however the projecting place are outside a size.) 

If thunder is detected, a non-voltage contact will be made ON or OFF for a definite period of time, and an alarm will be outputted. 
An alarm output is continued while there is danger of a thunderbolt.
