Are the power supply negative and output negative common?

no,unless the power supply for the unit and the output device is also common.

Works fine. I wired it to a horn and turn signal flasher to keep bears away from my tool shed in the mountains. They keep tearing up the door looking for mice. The screws for the in and out wiring are a little tricky though.

It is according to what you use for your power supply !! I Use A 12 v-dc Battery And a 12 v-dc Solar Panel To Keep The Battery Charged.12 V + In 12 V + Out / 12 V - In 12 V - Out. so your answer is (YES)

On the input side are a positive and negative node to connect to a dc power supply like a solar panel or battery. On tje output side you get a lower voltage but higher amperage flow of electricity.

Unless I am mistaken, your PC has an external power supply. So I would have to say no.

Well it looks like it. This Premium external power supply is rated at 5v 2 amp(2000 ma) output. You are now using a 5V 700ma output. From reread the info on the Premium external power supply the input voltage matches. As long as the replacement power supply output voltage match (5V) and the current equals or exceeds the power supply you should be OK. Hopes that helps.

No, this produces no negative voltage. The "-" terminal is marked to indicate what you would normally refer to as DC ground

Hello- This part is just the power supply side. I have had no problems with the part.

I feel I can safely say no here.Most audio amps that require dual supplies of the same voltage tend to require negative voltage on one pole, AKA a ground, 12v, and -12v..this power supply does not have a negative voltage output. If it requires two independant 12v rails, still no - this power supply has a single 12v rail with multiple taps.The only suitable usage for this power supply would be single-rail 12v applications. I hope that takes care of your question - if not, please provide more detail such as model or part number of the amplifier in question.

The external case doesn't appear to be connected to any terminal, there are both + and - terminals for the battery and array. I don't believe it will matter whether your external system is positive or negative ground.

Take a digital Volt meter and it will tell you if it is positive of negative.Don

I remember inspecting it before I installed it - the power supply output was higher than the 75 needed - but don't remember the exact output

On the side of the unit, it says "7-9 Volt", and a diagram for NEGATIVE CENTER. This is important because most wall adapters are positive-center, and using the wrong one might burn out the machine (unless the circuit designers went the extra mile to protect against that, which I'm not going to try to find out).

The red terminal is POSITIVE and the black one is NEGATIVE. I do not understand F1 and F2, as it may be specific to your schematic or circuit.

Negative. Motherboard itself supplies the power, though I would recommend making sure it can provide the required 350W.

My power supply is similar and I have been using it for about a year now with no issues. I also use dual monitors. I'd at least try it out.

Not sure about that as mine is negative ground. That said, it should be ground polarity insensitive by reversing the connections.

I agree with T. Thomas, sounds like reversed polarity - it's easy to do as the documentation is not very clear on the wiring.
