Is it too hard to read what is write and than understand that??? It is NOT warning system at all, it is active electronic suppression system. It work on near IR wave length(maybe, just a maybe on two different wave length for two or more different ATGM systems). Each device produce around 120W(this I am read on some other forums so I do not know is it true or not, but it have a sense), it is connected with thick cable because it work on two car batteries (12+12=24V) and it have an autonomy for 12h.
Why I think and I am convinced that is suppression system, look at it lens. This lens produce wide beam light and they are to small for detector. For detector any type you need large sensor or more smaller sensors that will be coupled together. And that mean you will have one large lens or many more smaller lenses. And we do not see that, only one lens around 5-6cm. And there is current consumption for passive sensors, you do not need two car batteries, and passive sensor can operate on more longer times, active can NOT. Yes, they can but, (f...n but
), but there be more power sources.
Because it is active suppression system which produce 120Ws of power( I do not know is it for all circuits or just for one, but I think it is for one, it have a more sense), so you need to have a voltage converter from 24V to rated voltage of circuit, because this type of circuit can not operate constantly on rated power, there must be circuit board that will work in PWM mode (it is type of modulation and can more interfere with light signal of missiles) and supplying power to devices. It consume current (maybe up to 10A) and for that current you will need to have passive coolers and they are big. So this is reason why is this box so BIG. Look at Shtora, it have for one unit two large boxes one for Shtora and one for control electronic.
This device can not be wived by TC. TC work on different wave length.
