If you were starting to grow tired of power strips that all seemed to look mostly the same inside, the SA-1810 is definitely something different. Through clever use of magnetics, semiconductors and large capacitors, it achieves power line surge suppression that MOVs cannot match. Even after tweaking my surge generator model some more to get closer to 6kV/3kA, the peak output remained under 200V, well within even the most sensitive electronics' comfort zone.
I really liked the overall construction except for the use of RTV to secure the reactor instead of nuts, in equal parts because the RTV failed in my unit and if it had stuck, I would have had to pry it off for the tear-down. This would have likely involved mangling the reactor's sticker, scratching the reactor housing and bottom tray.
Despite its great surge elimination performance and build quality, I cannot help feeling like the $400 street price is still too steep for what it is and does. If you have a large collection of sensitive electronics to protect, though, it should be worth considering.
Thanks go to Nicholas from Caster Communications for having the unit shipped to me, Robert from ESP for sharing his engineering insight, and readers like you whose on-going interest in these stories drive the manufacturers' interest in participating.
