Can the converter give output of 80 VDC as input is 12 VDC?

That's what is claimed but you will get a tremendous amount of heat by doing that.

Duo,I believe you could do this, and your only concern would be overheating. I used this part about five months ago, with an ambient temperature of 25 C, and input of 18 VDC. I operated at an output of 60 VDC. At 75 VDC, I required an external fan.I speculate that the fins could transfer heat to the environment efficiently, but heat transfer is poor from the PCB to the fins. Temporary solution: block of ice. Though this might not be appropriate for your purposes.GrantMonrovia, Liberia

I checked the power supply to this unit and it shows 120-240vac on the nameplate for rated input voltage with 12 volt DC output voltage to the PolyCom. I think you will be OK.

instructions say power source is only 120V so I believe you need a converter.

Inverter needs 12 V input from the battery and will convert it to 120V for home use

I also bought this . It only works on a 24 volt dc system. Mine was not advertised to convert from a 12 volt dc source.

not unless they changed it in the last year. I bought mine one year ago and the transformer says: "input: 120Vac 60hz 80mAOutput:12vdc 200ma"

As long as the output is 12V amps do not matter. It's the 12V that is critical.

If you have a 12 volt dc input to 120 V AC output inverter then you would want them in parallel. That will give you about 18V to the DC input of the inverter. If you were to put them in series the you could have up to 37.4 volts DC going to your inverter and if it is a 12 V DC input inverter that could be bad, depending on the over voltage protection offered by the design of the inverter.

any 12 volt dc current is usable, weather it is from a battery or a transformer pack it does not know the difference - be careful to get the polarity correct...

You can do that. However, please understand that there will be voltage drop along the wire and you may not get 12V to the converter. How much voltage drop it will be depends on the length and quality of the wire, also the power consumption.

No. Voltage is 12VDC. Wall plug is 120VAC. You would need a transformer to convert to 12VDC.

No, this is 120V. Not sure if it would work properly with a converter or an adapter. Would ask the manufacturer.

Yes, you just need to purchase a plug in transformer to convert the 120v ac to 12v dc. 500ma should be sufficient

Sorry, I'm not qualified to answer that. If it puts out 110/120 volts I don't see why not. Call up the mfr. or distr.

No. If you use a rectifier you would have less than 12vdc. I am pretty sure you just need to buy a 12vdc power supply

Yes. If your LED is 30W and runs on 24-30V then it draws 1.33-1.0 amps respectively. The converter can output 3A continuously and the requirement on voltage is that the maximum ratio of output voltage to input voltage is 3. So since you're putting 12V in, you can get 24 or 30V out easily, and this still keeps you under the current limit. Hope this helps, the converter has been good for me, it's very stable on the output despite a changing input. If I can be anymore help let me know. -Brian

No, this goes the other way (120V-&gt;12V). You need an inverter that goes from 12V-&gt;120V.
