Does this have an adjustable output? Example - can I run 26.4V in and have 12 to 13 out? Thanks.

A pulse width modifier does not change the voltage, so you get out what you put in. What the PWM changes is the proportion of time when the voltage is available. Hence a 12 volt motor changes speed even though it is still getting 12 volts, because as you turn down the control knob, the width of the 12-volt pulse narrows, and the no-volt gap increases. At full speed, each 12-volt pulse is adjacent to its neighbors, appearing as constant 12v. As you reach zero, the width of each pulse is so close to zero, and the gap increases to almost the entire width of the pulse. The motor cannot find enough power to turn, even if a scope shows 12v peaks. Think of your power as a rectangle of voltage (height) and time (length). Stack these end-to-end and you have pure 12 volt power. However, if you keep the length of the rectangle the same, but only supply voltage for the first half of the rectangle, you have supplied 12 volts, but for only half the time. During the "gap", your motor coasts. The average motor speed is half of what it was when the rectangles were full of power. As you turn the knob down further, you are only filling the first 10% of the rectangle with 12v. The motor runs at full speed for 10% of the time and coasts for 90% (of course, the motor cannot accelerate to full speed instantly, so this is a theoretical example - in practical terms, the pulses are so close together that the run and coast intervals are not visually detectable, thought they would show up on a scope. Long answer, but I was not sure about your level of expertise, so I tried to make it understandable on a fairly low level.

I did. Its hard to explain,but as you adjust knob for speed control your changing volt in a way.I had 24 volt. DC going In an it ran a 12 volt DC motor with no problems.

yes, the PWM control allows variable output as long as the input voltage is higher than what you want for the output. frank

There is a tiny lever on top of the blue box (between two capacitors). You may turn the lever with a small flat screw driver to adjust the output voltage.

No...it is a switching type power supply/switching regulator and a change in input voltage will make almost no difference in ourput voltage. At some point as you adjusted the voltage down you would probably burn out the power supply as it tried to heroically make full voltage output. Don't even think about trying it.

The unit I got was preset to 11.99 volts output. I used a voltmeter to set it to 12V output. The input accepts a range of voltage and does not need to be set. I connected my 20V and then 12V rechargeable batteries and the output voltage did not waiver.

It hasn't in my case. Most electronics logic and components sensitive to a .4 Volt difference run at 1.8V, 3.3V or 5V, as well as the fact that batteries voltage can drop up to a volt or more from full to empty, so there is circuitry to drop a range of voltages down to logic levels and that circuitry should handle the extra .4 volts. That would be the close to limit in my case, though, at which point I'd confirm against Sony branded equipment (the sony adapter is 7.6V as well).

Well, the manual says it works with a 6 voltage system, and i didn't check what my voltage was when i was using it. So the only way is to try to find out. Hope it doesn't blow on you.

If you're looking for the "preout" rating - the maximum is 4V. If you're looking for the output rating of the unit, that's measured in watts and it's 22W per channel. If you're really looking for power consumption, that's rated in amps, and it's 10A.

Im not really sure what you are asking. But if you're asking for the voltage range of this item, output is 24V (actual is 26.8V). Input is 12V

You can use a voltmeter to detect the output as the potentiometer is adjusted. The output does hold it's setting very precisely so once set to output a certain voltage it will maintain it accurately without readjustment. Input is variable so you can hook up any source from 4V - 30V, meaning no adjustment is needed for the input.

Absolutely not. It puts out anow industry standard 19 volts and about 5 amps. The only variable is the male plug inside and outside diameter of the multiple plugs

I'm sorry, seems it doesn't. It reads out "input DC 11-30V. Output 5.0V 700mA"

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

hi friend, the item is a converter adapter. Output is DC 13-16.8V. If your Power Supply System is during the value. It's ok

There is a screw-like knob, between the two blue output blocks in the photo, which can be turned with a screwdriver to change the output voltage. You'll need a voltmeter to measure the output in order to set it to a specific value.

The only adjustable thing I can find on it is that you can apply either of two voltages to it either 12 or 24 volts dc to it with the consequence of a same output 5 vdc out of it. That is the only adjustable part I can see on it.

I just tried 2 18350s witch were both about 4v so that would bump it up to 8v. It came on then dimmed out. Prolly has circut protect and won't allow above a certain volt or amp. Not sure witch but I would have to say it probably won't run on CR123a.

I'm not exactly sure that I understand what you are asking, but here's my best shot. Hope it helps!Short answer: No.Long answer: If I understand this correctly you have 12V LEDs and a 110V dimmer? This power supply regulates to a target voltage around 12V optimally independent of the input voltage. Simply put, if you put 110V or 90V to this it should still output 12V. There is a voltage adjustment on here that you could use as a dimmer that lets you adjust the regulated voltage from 10-18V. So if you don't need a remote dimmer adjustment and this is enough variance for you then it might still work. Hope that helped, and let me know if you have any other questions!
