I have an ELNA 3210 is 220v I live in Florida and need voltage transformer. from 220v to 110v for it and how many watts does it need? Thank you


From this document
http://edrenzi.com/Code/Trans%20(1p).pdf
the power is going to be the same as it was with 220V
However you need a step up transformer

if the supply voltage is 110V then the primary voltage needs to be 110V and the secondary voltage needs to be 220V dependant on your Elna needing 220V to run.
Does the ELna have a power rating plate at 220 V AC and if not does it have a current rating at 220V as power = voltage x current
so if it was 1 amp at 220v the power rating would be 220 Watts
When a transformer is involved the current on the primary coils of the transformer will half due to the 1:2 ratio of the transformer and will drag the same wattage as 220 V .
Another consideration is the frequency of the supply I am guessing the ELna is looking for 50 Hz and I think Florida will be on 60 Hz - not sure if this will be an issue in the ELNA but there are frequency adapters on the market to convert 60 hz to 50 hz if it is an issue.

You might be able to check the elna circuitry to see if it has a transformer inside it that you might be able to change to run at 110V down to whatever the elna runs on internally at its internal transformer secondary voltage.
Also check there is not a switch on the elna to switch from 220 v to 110v on the unit - not sure if it has this feature ?

I have bose wave with input voltage 110 volts but i want to change it 220 volts where i can buy a transformer


Check the back or the bottom of the Wave unit for the input voltage rating. If it has a universal power supply, it will show something like "Input voltage 97-243 VAC 50-60 Hz," i. e., the input voltage rating spans the full range from 110 VAC US to 240VAC Europe. In that case, all you have to do is get a power cord suitable for the power in your area.

I checked the specification in the on-line owner's manual, but it wasn't helpful; it said the input power rating is "220V-240V
50/60Hz 60W max" We know it works on 120 V, so the 220V in manual may be a typographical error. Go with the information on the unit case. If it says "120 V 60Hz" and nothing about 240 V, then you would need a transformer rated for at least 70 Volt-Amps (60 Watts plus a reserve factor so you don't have to worry about overloading it).

I tried checking my favorite site for electronic products such as travel transformers and adapters (MCM Electronics), but as of this time they were having server problems. Note: they may have the 240 V version of the power cord, or you can check whether Bose sells it separately.

Need a power transformer from 220v input to 120v output


Yes, you need a step down transformer. These are often rated in watts (the power rating is the same on both sides of a transformer) so it is easy enough to match this with the power consumption of the stereo. Apparently you will need about a 4kW transformer eg

Want to convert hp laserjet 3055 from 110v into 220v


You maybe able to get a new 220v power supply board and swap it out in the printer.
The other way is to get a 110v to 220v step up transformer, make sure the current rating matches or greater than the printer's requirements.

Hi, i have a dream machine sony ICF-c218 by mistak connected to 220v the original transformer is 120V & i also would like know the output voltage of this transformer so that i can change it 220V p


My self sushil from india pl.find the details
yellow-blue is 3.2 VAC
red-white is 4.2 VAC.
Clock is well functioning without frequencies difference error. I think the clock is using crystal for pulses generator instead of AC power supply frequency.

Rewire blender


Simple answer; no.I don't know where you are but step-down transformers are a pretty common item (some are even reversible) but make sure that the transformer's power rating is adequate for the blender; for example: if the blender is rated at 200 watts or 1.8 amps (roughly the same at 110V) use a transformer rated at least 50% higher to avoid having the output 'sag' under load.

I have a LG LRE30453SW Electric Range and the relay pcb keeps going bad. I get an F7 error when starting the oven. The first time I noticed the black line in, from the power terminal, to the relay pcb was...


First, check the 220v line and breakers are properly grounded and that you are getting a constant 220v at the plug. Then you will need to check the transformer on the unit.To test a transformer you need to know what type of transformer it is first. There is a step up transformer which steps the voltage up and a step down transformer which steps the voltage down.
You will still test the transformers the same way for step up and step down transformers. If it is a step up transformer apply the incoming power to the transformer or plug it up. Now take your multimeter and place it on the AC volt scale and test the voltage if the voltage on the data plate says the transformer should step up to 220 volts and it doesn't then your transformer is bad.
Now repeat the same steps for a step down transformer. Plug up the incoming or primary power and test voltage on the outcoming or secondary side the voltage should step down to the proper value. If you don't read any voltage on the secondary or outgoing side then the transformer is bad.
To read the voltage place the two meter leads on the secondary side, or the side you will plug your equipment into. If the secondary side is an outlet then place the two meter leads into the top two slots in the plug and read voltage. You also want to make sure the incoming power is working as well. Otherwise you will be reading a bad reading every time.
If all that looks good, then you will need to replace the control board. Here is a link to the parts for your range.
