Ferrum ERCO, desktop high end just became a thing...
oh, and it’s pronounced ertso, not airco
Like a top chef who uses his ingredients freshly and grown from his own garden, we integrated parts of the awarded HYPSOS technology and lend some of OOR’s magic to lay the first bricks for ERCO. Then we proceeded to add our culminated 20 years’ worth of experience in making DA converters. And man, did we pull it off. We managed to get the best out of our two winners and put it in our new sibling, adding awesome DA conversion to the mix.
Unique output cable design: two wires delivering the power and two wires providing the feedback to ensure flat voltage at every moment. We named this technique Ferrum Power Link (FPL) and it eliminates the harmful effects of the cable's resistance effectively improving transient response. The current delivery speed at the powered device's input is significantly improved.
ERCO comes with a carefully selected DC power adapter. To get the most out of ERCO you can connect it with HYPSOS using our proprietary Ferrum Power Link DC power cable. This FPL cable can be ordered separately.
