In one way Tellus II is old stuff in new packaging. But at the same time it's a totally new groundbox that will open up for many new possibilities. Left and Right outlet are two separated Silver Minimus and the outlet in the middle is the same as a Silver Minimus and Atlantis Mini built together in one chamber.
In other words, its a "entry level Poseidon".
It offers three dedicated ground points which are totally separated from each other. For further information about all the options, please take a look at the Poseidon. Tellus II work the same way.
Note: The Tellus or Silver Tellus is not designed to replace the protective ground on your electrical mains!
