(in message ): The reason I prefer a true Uninterruptable Power Supply (UPS) instead of a surge protector is that I've seen my UPS switch over to metered battery power up to two seconds before I see a flash of lightning (or hear close thunder). By strict definitions, that's not an UPS but a SPS (Standby Power Supply) because it - as you say - "switches over". In an UPS, (Uninterruptable Power Supply) all power is through the battery all the time; there's no lag because there can't be one grin. I've got an old APC 600-watter that's a "legit" UPS but it's the old style that has to be sent back for a new battery sigh. So we're using a couple of SPS's until my ship (or a stern-wheeler - whatever) comes in. I would think that this "switching over," effectively cutting out the overloaded circuit, is a much better method of protection than trying to dampen a big lightning (or other) surge as the surge protectors do.
