Utterly frustrated with Tunze streams..

Just measured the output from the Jebao controller, it's 5v max.

Now the weird part. With the Profilux set to 0-10v I get 4.89v at the control circuit out to the pump. There must be a resistor in the adapter for the Profilux circuit.

Temped to just hook them up to an old wave maker power bar.
