How well is the DC voltage regulated? What is the ripple factor?

HiI've checked the ripple factor and always looks like a 12.6 or 12.7, no more. In my opinion it's a great cable. I am really happy with it.

I can not give you any technical options but functionally it operated as advertised. Kept my items in the cooler cool and that was all I wanted.

Hello, Thank you for your kind email. please note that the Rated Voltage of this item is DC12V,and the Output Speed is 3.5RPM. Please feel free to contact us if you need any assistance in future.:) Have a nice day. Best regards, dengfang

It should always read 115V out (same as input). It's not a voltage regulator. It controls speed by PWM (Pulse Width Modulation) which means it changes the AC waveform. Look up PWM on Wikipedia.org if you'd like a more detailed explanation.

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.

Hello, I have purchased 3 of these for camping and they are 12V DC. That is just a typo in the description. They work great!

That's what I've got it plugged into. Works great (for the power consumption - I only have a 300W supply)!

Looks like the same one I bought. I used a 12 volt DC 1 amp output converter. Think I got it from Radio Shack. It was plenty loud with even a smaller amperage converter I had, but I thought it might overdrive it so I got the 1amp just in case.

both the speed and colors can be adjusted, and working power DC 5-24V will be OK. thanks!

DC. Depends on how many amps that converter is rated for and how many volts at your input. At 12 volt input you will needs to pull 8.3 amps.

HI I am not sure what are you asking me, beacuse I am not know too much technical stuff, if you explain to me I will be glad to help you, but, as far as this item, works excellent, sound pretty good, and I am not see any voltage fluctuations.

Yes, Max current allowed is typically much lower for dc compared to ac for a given switch.

I received an Amazon message requesting an answer to your question; problem is, I have no idea. It works OK with 12 V DC.

J. hit the nail on the head. Though, my unit is slightly different in that at half way the voltage sits at 11.2. I will say that the touchy scale in the first half of the knob's range can be slightly annoying if you want a mid voltage, but I find it to be a minor inconvenience and am extremely satisfied with the quality and features of the Lamptron FC5V3

Probably not, unless you are going to draw large currents on the output. As you can see from the picture, it has 2 caps on the board, both 220uF, one on input, one on output. For reasonable loads (like 1/2amp or so) the 60Hz ripple probably won't show up on the output. In any case, if you do see output ripple, you can always add a cap afterwards. But I would try it without an extra cap first.

I bought a new 700W power supply, but it's not even breathing hard, even when I push the envelope! I'd always be over-engineered than under-engineered. It will last just about forever because its not being taxed or pushed to its limit.

I haven't try it w/12VDC but... it does have the connector for DC on the side.

datasheet is SLC-12VDC-SL-C, you're good from ~9-14 vdc. I use the battery/charge controller for power, not the pv.
