Can a 500mA transformer be used to operate a circuit requiring 1amp12w?
No because that transformer can only supply a ½ amp so it would seriously overheat if a 1-amp load was connected to it.
How many 240 volt 4.9 amp draw lights can be run on a 15 kva 2 phase transformer?
The lamp uses 240 x 4.9 VA, that is 1176 VA, so a 15 kVA transformer, which is 15,000 VA, could feed 12 lamps.
How many watt transformer is needed for 2.5 amp motor?
Need to know the voltage of the motor and primary voltage of the transformer.
Can you use a 30 amp disconnect switch for a 30 kva transformer?
im have a 30 kva transformer 3 phase 480v 80 amp panel 120v what size disconnect should I use
Can you convert a Makita 5007mga from 120V to 240V?
You need a step down transformer. A transformer that will step 240 volts to 120 volts. Check with Radio shack or your local electrical supplier. This saw draws 15 amps when it is running (1800 watts). It will draw close to 30 amp instantaneous when it starts. The transformer that you will need, should have at least a 2KVA rating. Even better a 2.5KVA.
Does a 3 phase step up transformer placed before a rotary phase converter reduce the single phase amp draw?
No, your amp draw will not be reduced. It will actually be slightly higher because the transformer will not be 100% efficient. Contact TEMCo Phase Converters at (800) 613-2290 if you have any more questions.
Can you use 20 kva transformer in a home?
Yes you could use a 20 kva transformer in a home. Stymied as to why it would be done though. You would need at least a 100 amp service to the home to energize the transformer. Primary side of the transformer would draw 83 amps at 240 volts. If the question was to supply the home, again yes. It would be 100 amp service equipment that the transformer would feed into.
How do you find the maximum amp draw on a step up transformer?
It depends on the load. A good transformer has over 90% (some as high as 99%) efficiency. So the power drawn by it is a function of the power in the load, plus a small amount due to losses in the transformer.
Can you sub a 240 volt 1.5 amp transformer in place of a 240 volt 3 amp transformer?
If the load you are connecting to the transformer uses 1.5 amps or less, yes.
Will a 4.74 amp transformer fry a computer designed for a 3.42 amp transformer?
No because the current rating of the transformer is a maximum allowable current. If the computer still takes 3.42 amps it will be OK provided the new transformer supplies the correct voltage.
Can you run a 40 amp 10KW oven from a 32 amp 12 KW transformer?
No; drawing more than the rated amperage from a transformer will cause it to overheat.
What is the amp rating of 100va transformer?
The amp rating for a 100VA transformer will vary depending on the actual voltage of the transformer. Transformers have both a primary and a secondary voltage.
What is the fuse rating for 5MVA transformer?
50 amp
What happens to amp draw as static pressure increases?
As your static pressure increases your Amp draw will drop
Can a 500mA transformer be used to operate a circuit requiring 1amp12w?
No because that transformer can only supply a ½ amp so it would seriously overheat if a 1-amp load was connected to it.
How many 240 volt 4.9 amp draw lights can be run on a 15 kva 2 phase transformer?
The lamp uses 240 x 4.9 VA, that is 1176 VA, so a 15 kVA transformer, which is 15,000 VA, could feed 12 lamps.
What device raises voltage?
Depending on your application... Use a voltage dividor (two resistors) if it doesn't draw a lot of current. You could also try a voltage regulator or using an op amp as a buffer, with the input the voltage you want. That voltage could come from a voltage divider, since op amps draw extremely low current.
