In that case power in equals power out. Use the total wattage, plus 20%, as your minimum power requirement. Example 2, how much power a computer has in watts, Example 3, conversion from going to watts for a freezer. Hastyface. To convert from VA to Watts you simply multiply the VA by the Load power factor , as shown by the formula of VA to Watts.
RapidTables.com | Some say output, but not input. The power a device draws is defined by it's design. Where: Watts = Active power (P) or watts, this is the value to be found. Find out more about how we use your information in our Privacy Policy and Cookie Policy. I was saying, the 20A max receptacle rating for the 120VAC stand is less than the max receptacle; why does the U.S. have to have 220VAC for things like washers and dryers? Which one should I look at, also while doing the convertion to 220v from 115v or so on, do the wattage gets divded by 2 as it's half the volts we use in America? 8100 / 115 = 70.4 amps How many volts are there in 1367 watts? If you have the watts,divide it by the volts to get amps. by Andy Wigner on 06/07/05 at 06:18:23 Thank you very much for your help Mr. Fogt. In the US we use 115v - 125v and in Argentina it's 220v.

Same thing with these 1.2kw psu's. Electric current in amps (A) to electric power in watts (W) calculator. Answer Save. 1 decade ago. Basically, it would be better overall if Europe followed Japan's lead, so the whole world can just use 120VAC, which would cause things to consume less energy. For old personal computers (PCs), this value can be 0.60 – 0.75. natchomomma. For example 1.5 amps * 12 volts = 18 watts Source(s): My brain. An example of energy consumed in watts is the filament in a bulb. What will be the wattage of the refrigerator ? Note: The wattage's given below are estimates. Table of equivalences from watts to watts for systems that have a power factor equal to 0.8.

If you keep the 220VAC standard, then that could encourage things to use more wattage. There were so many quotes It was hard to follow some of what was said. People just need to get better circuit breakers, and PS Audio receptacles; if they have any aluminum house wiring, they need to tear all of it out and replace all of it with copper wiring. The surge range for the 120 VAC input standard (assuming there is no auto switching transformer) is [>120VAC,
http://en.wikipedia.org/wiki/Conservation_of_energy, http://en.wikipedia.org/wiki/Quantum_computer. The apparent power in VA is used to simplify the power values , which facilitates the calculation of current consumption.

For example, a 100 W bulb that is left on for 10 hours consumes 1000W-hour of energy (100W x 10 hours = 1000W-hours = 1 kW-hour). A clothes dryer has a power of 2800VA and a power factor of 0.91 , how much power in Watts does the dryer consume? Ampere (amps or amperage) is an SI unit of electric current and is denoted by 'A'.

Re: Convert Voltage/Hertz to Watts? watts = 15A × 12V = 180W. I brought a Z-5500 5.1 speaker set, an xbox 360 and netgear router, all of them require transformers for 220v. You must log in or register to reply here. be approximately equal to 0.8: For AC power supply, watts are equal to the power factor times amps I believe the idea behind it is it's safer and cheaper to do it that way. In a dryer for instance I believe the motor that turns the drum is a 120V motor connected to one of the two 120V feeds. times volts.

The apparent power (measured in VA or voltamperies) is a mathematical combination of real power and reactive power. watts (W).
The real power (measured in watts) is the portion of power consumed in a machine . Since many types of equipment are classified in watts or watts, it is important to consider the PF when sizing them. 115v / 60hz = how many amps? Privacy Policy | In the US we use 115v - 125v and in Argentina it's 220v. The Watt (Watts) refer to the “real power” , while the volt-amperes (VA) refer to “apparent power “. some devices do not need a stop down as they do it themselves. 1 0. Assuming a power factor of 0.8 the result would be 400Watts. So I had it backwards. The easy response is 4.8Watts, taking into account a power factor of 0.8 and using the VA conversion formula to watts: 6VAx0.8 = 4.8Watts. Table of VA to Watts for UPS (Power factor of 0.8): Convert candela to lumens using this calculator – I (cd) to ϕ (lm), BTU/hr to kW calculator – Explanation, examples and equivalence, AWG to mm2 equivalences for electrical cables and conductors, Impedance Z calculator, formula and table according to IEC.

I'm taking my time to elaborate and I'm not the one who was talking shit. If the PSU companies had just capped the wattage of their products at like 800W, then not only would video cards consume less power, but they'd also run cooler. You can change your choices at any time by visiting Your Privacy Controls. Everyone is on the 220V boat except America.

To combine the real power of several DC or AC devices, you can simply add the individual power values ​​in watts of each device to get the total power (the sum of watts is done linearly). I was talking in terms of an entire appliance designed to operate at different voltages, since we're discussing computers here. 2 Answers. Rta: // As the formula indicates, you must multiply the VA by the freezer power factor , as follows: 5000VAx0.89 = 4450Watts.
