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 taken on the 5V is always divided by two to know the current taken 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.


  • Offers up to one amp of precise 5Volts
  • Takes its power from where you won’t use it: the negative rail
  • Gives you back the +12V power previously used to make 5V
  • High efficiency conversion: Every milliamp delivered on the 5V rail only draws around half as much milliamps on the -12V rail
  • Soft-start prevents current inrush at power-on
  • Tolerates wide voltage variations of the -12V source
  • Miniature module 20x28mm - 0.78x1.10"
  • Adjustable output voltage - delivered calibrated
  • Protected against:
    • Current overload
    • Input overvoltage
    • Overheating
    • Short-circuit
    • Reverse insertion
