pedal power 2 plus and 24v ehx qtron fail

[alec112591]

The 24V Q-tron should be powered using our 2.5mm Voltage Doubling Cable connected to any two of outputs 1-4 with the corresponding DIP switches set away from Normal.

I recently ordered a Q-tron+, and this post has me confused. Shouldn't the Q-tron be powered from outputs 5 & 6 (with the DIP switches set away from Normal) since outputs 1-4 have a max current of 60mA when the DIP Switch is set away from Normal? The power adapter for the Q-tron is 100mA.

In fact, it's fine as suggested:

To power the Q-Tron (or Q-Tron+) use any 2 of Pedal Power 2 Plus outputs 1 - 4, DIP switches set AWAY from normal and a Voltage Doubler Cable (reverse polarity, 2.5/2.1mm), part# PPEH24

Also... 60mA was a conservative limit (based on the original Pedal Power) but with a Pedal Power 2 Plus in the 12V setting it's only a slightly less than 100mA.

And, the actual current draw of the Q-Tron (or Q-Tron+) is only about 80mA.

Cheers!

Thanks Ben. Is there a reason you would not want to use outputs 5 & 6 (with the DIP switches set away from normal)?

Yes, the reason is that outputs 5 and 6, DIP switches away from NORMAL, is the 12V unregulated (the voltage will vary depending on the actual load of the connected device itself) setting.

As such, a pedal with a low current draw (less than 100mA) will "see" a voltage greater than 12V... perhaps 13V, and a thus when doubled 26V, which is a bit too high.

Cheers!
