Can it make positive and negative voltages?

Connect to the red and black terminals (not green!) and just put two equal size resistors on a breadboard. Middle will be zero.For example, output 12 volts and use the middle as ground. You then have 6V and -6V. You just can't be connected to earth ground, which is usually denoted by the color green.

Not at the same time time (it's a single output supply). But it is a "floating" supply. By connecting the red output to another supply's ground or common , the green output will be "negative" relative to the common connection.

negative or positive voltage is simply a reference to ground. reverse your power connections (leads) and you now have negative voltage. it does not have a dual output for both positive and negative voltagesgood luck

Yes, I have the same set-up, connect the batteries to all three batteries. Positive and negative to all three batteries.

Yes that's the neat part of this device there's a tiny gold screw you can either adjust to go up or down in voltage just hook it up to a multimeter and set it to the voltage you want.

No, the idea for this one is a booster. The output is variable, but I don't think there's much overlap between its acceptable input voltage and its output. From my unit, it certainly couldn't go as low as a 5 v DC output.

Get the voltage and polarity right and you should be ok. Just be careful not to fry it.

I haven't tried it, but voltage is voltage. There's no reason it wouldn't work.

No, it is 9V, I am sure about that.The polarity is what I doubt, but is easy to check. If you pug it and the light does not turn on, it is the other choice.You cannot damage it by connecting it inverse.

i believe the answer is yes but to be on the safe side you might think about a voltage down-converter; i just examined the tool and the owners manual but nowhere can i find allowed input voltage; nor can i find their company website to answer your question; i would expect one of two things happening however: 1. the electronics might blow on plug-in - or - 2. you MIGHT be able to operate the device to half-scale; i've been finding out the hard way: cheapest is not always best (you get what you pay for)

It has a voltage range. U can try it if it plugs in but I wld have to see ur setup.

I just used a 12v adapter I had lying around. I cut the end off and used a multimeter to make sure the polarity was correct and hooked it to the board. Please, do be careful about the where you put the positive and negative. I remember reading on the net that this device won't protect itself from reverse polarity on the dc voltage. Meaning, the circuit board will be ruined.

I no longer have the literature on it, but I doubt if it has the capability to accept both voltages. You could contact the manufacturer.

Yes you can switch 2 different voltages through the rely just make sure you connect to the right terminal. Les @ McCloud Electrical

My answer would be NO. Does not put out that kind of voltage. Does good on 12 VDC.

I cant say except that 12 VDC doesn't mater about polarity. 12 VAC is only 8.5 volts effective or / root mean square

If you switch the input polarity the unit will not function at all. It has a diode. The unit will not light up. It will not turn on. It will not work. DC polarity must be connected as shown on diagram. Can you tell me why you wanted to change there polarity?

yes, if you wire it correct. there are only three wires, ground, positive and negative.

You should be able to wire together all positive an all negative and just connect one + and one - to the battery. The current draw is fairly low so it should be no problem.
