What would the control voltage be for a transformer marked 240v 24vac?
A control transformer marked 240V - 24Vac would have a control voltage of 24 volts.
A single phase transformer has an input voltage of 240v and output voltage of 50v and a rated input power of 4.20kW if their is 1344 windings on the input side how many on the output?
There is (240 / 1344) = 179 milli volts per turn. The output voltage is 50 volts, so 50 / .179 = 280 turns on the secondary.
A 240V to 480V Step up transformer with a load of 85 amps at 480v what amperage will the transformer draw if the primary is 240V?
Since this transformer has a ratio of 1:2 the load current on the 480V side just has to be doubled. 85 x 2 = 170A on the primary. 40.8 KVA transformer. To prove this just find the KVA of both sides and they should be equal.
What KVA transformer is needed to convert 480v - 240v 13.5A load?
Ohms law says that watts are equal to volts times amps. 240v X 13.5a = 3240 va VA / 1000 = Kva So, your load requires 3.24 Kva. The transformer should have a rating greater than this as a safety factor, so you would choose the next larger size, in this case probably a 5 Kva transformer with a 480v primary and a 240v secondary. Your local electrical codes may require a larger safety factor, so you would want to consult them before buying the transformer!
What is the turn ratio of a transformer if the primary voltage is 240V and the secondry is 12V volts?
240 / 12 = 20
A transformer has a primary volt of 240v and a secondary volt of 48v what is the turn ratio?

How do you use Japanese light bulb 100V in Malaysia which is 240V?
get a step down transformer whose output is equal to the voltage of your bulb
Can you lower 277v to 240v?
With a transformer.
What would the control voltage be for a transformer marked 240v 24vac?
A control transformer marked 240V - 24Vac would have a control voltage of 24 volts.
Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
If the loads were only 240v on a single phase 240v system with a center tapped transformer the neutral conductor would carry?
If a load were only 240 volt on a single phase 240v system with a center tapped transformer the neutral conductor would carry no current.
How is possible to increase voltage rate of a transformer?
Yes, first find out how many volts you need on the output. For example, I'll go with 240V for a step up transformer. You would want to put some 10-14 guage wire on the secondary of the transformer, at around 240-250 turns on the transformer. If you can fit thicker wire, then it'll handle more current, but it may blow a fuse once you get such a big transformer.
How can you use step down transformer of 240 v ac to 24 v dc as step up transformer?
A step down transformer has a higher voltage (in this case 240v) primary and a lower voltage (in this case 24v) secondary. A step up transformer has a lower voltage primary and higher voltage secondary. In reality the transformer doesn't care which is which, so if you wire the 24v side as the primary and the 240v side as the secondary, you have a step up transformer. You might want to stick a fan on it to be sure it doesn't overheat, but that's all you need do.AnswerFrom your question, it sounds as though you are describing a power supply, rather than a transformer, as you specify the output is 24-V d.c. (direct current). Unfortunately, you cannot apply 24-V d.c. to the output side of a power supply, in order to obtain a 240-V a.c. output at the input side! This is because a power supply consists of a transformer to step down the a.c. voltage, and a rectifier (and, possibly, a smoothing filter) to produce a d.c. output. Applying d.c. to the input of a rectifier will not produce the a.c. necessary to run your transformer in the opposite direction!

There is (240 / 1344) = 179 milli volts per turn. The output voltage is 50 volts, so 50 / .179 = 280 turns on the secondary.
Which is more efficient 12v or 240v downlight?
If they are both using the same watt globes the 240v is slightly more efficient due to small losses in the transformer.

Can a 240V - 110V stepdown transformer be reversed to take a primary load of 180V to secondary 240Volts?
No
