Klavis NoDrain


Regular price CAD$36.00

Reclaim your unused watts !

Did you know that typical 5V adapters draw 240% of the actual wattage they deliver, with 140% being wasted as heat ?

Moreover they take it from your precious +12V rail.

Beating even other switching-supply adapters, the NoDrain converter takes its power where there is plenty unused: the -12V negative rail ! *
You can safely assume that the current drawn on the 5V adapter will take half as much on the -12V rail.

The NoDrain adapter does its conversion with high efficiency.
With 1 amp available, you can distribute the 5V from the NoDrain to several busboards.
Thanks to ultra high-speed switching technique there is no noise to be heard.

Just plug a NoDrain in one of the connectors at the back of your rack and you’re done.
