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 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.
How do you wire 240V to 480V dry type transformer 15kw?
To wire a 15 kW dry type transformer for a 240V to 480V configuration, first ensure that the transformer is rated for this voltage conversion. Connect the primary side to the 240V supply by connecting each of the two primary terminals to the respective phases of the 240V supply. For the secondary side, connect the output terminals to the load requiring 480V, ensuring that the load is compatible with the transformer rating. Always follow local electrical codes and safety standards, and consider consulting a licensed electrician for installation.
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 is the turn ratio of a transformer if the primary voltage is 240V and the secondry is 12V volts?
240 / 12 = 20
If you have a 120V Sony stereo amplifier that you plugged into a wall transformer to step down from 240V in Denmark and it worked fine then zapped can you replace the fried component to accept 240V?

How can a buck-boost transformer be used to convert voltage from 208V to 240V?
A buck-boost transformer can be used to convert voltage from 208V to 240V by adjusting the winding turns ratio to either step up or step down the voltage, depending on the specific configuration of the transformer.
How to convert 120v to 240v for electrical appliances?
To convert 120v to 240v for electrical appliances, you can use a step-up transformer. This device increases the voltage from 120v to 240v, allowing you to safely power appliances that require the higher voltage. Make sure to follow all safety precautions and consult a professional if needed.
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.
How can you convert 240v to 120v for ac?
Use a step down transformer 240 primary to 120 secondary. You must know what the connected load (amps) is so that you don't overload the transformer. Small transformers are rated in VA.
How do you use Japanese light bulb 100V in Malaysia which is 240V?
To use a Japanese light bulb (100V) in Malaysia (240V), you will need to use a step-down transformer to convert the voltage from 240V to 100V. This will allow the light bulb to function properly without being damaged by the higher voltage. Make sure to use a transformer that is rated for at least the wattage of the light bulb to ensure safe operation.
Can you lower 277v to 240v?
Yes, you can lower the voltage from 277V to 240V using a transformer. A transformer can step down the voltage while maintaining the same frequency. Make sure to select the appropriate transformer with the correct voltage rating for the input and output you need.

How do you run 12v winch off 240v power?
You can use a step-down transformer to convert the 240V power supply to 12V required for the winch. Make sure the transformer is capable of handling the power requirements of the winch and is properly wired to ensure safety. It's recommended to consult with a qualified electrician to set up the connection safely and effectively.
How do you wire abuck boost transformer from 208 to 240?
To wire a buck-boost transformer from 208V to 240V, connect the 208V input leads to the appropriate taps on the transformer to step up the voltage. The output leads on the transformer will then provide 240V. Be sure to consult the transformer's wiring diagram and follow all safety guidelines during installation.
Can you convert a 120 volt Yamaha clavinova to 240 volts?
No, it is not recommended to convert a Yamaha Clavinova from 120 volts to 240 volts. This could damage the instrument and void any warranty it may have. It is best to purchase a Yamaha Clavinova that is already rated for 240 volts if needed.
