Knowing the RMS current helps you to correctly size the cables and circuit breakers, protections, breaker or fuses that supply power to your device. P in watts (W), divided by square root of 3 times the This website uses cookies to improve your experience, analyze traffic and display ads. A computer has a power of 500VA and a power factor of 0.92 , what is the power in Watts of the computer? For example, let’s convert 120 volts to watts, for an AC electrical circuit with 15 amps of current and a power factor of .9. Volts to watts calculator DC watts to volts calculation. V (V) = P (W) / I (A). × PF × I(A) ). However, we must first have a brief discussion about power terminology . Also, explore tools to convert watt or volt ampere to other power units or learn more about power conversions. Watts to VA calculator VA to watts calculation. A volt-ampere (VA) is the unit used for the apparent power in an electrical circuit. Note that rounding errors may occur, so always check the results. Therefore, you will want to ensure that the cables and associated circuits that supply power to this equipment conform to an amperage of at least 2.5 A RMS. If you have any questions about this tool or anything related to security camera systems, please contact Mike at For many newer types of equipment, such as computer servers, the typical PF is 0.9 or higher . This table shows the commercial values ​​of some UPS with power factors equal to 0.8: Both watts (Watts) and volts-amps (VA) are units of measurement of electrical energy. You pay your utility company for watts (W) expressed as energy, which is the energy consumed over a period of time and that generally the utility company shows in kilowatt hours. × PF × I(A) ) ≈ P(W) / (1.732 Power in watts (W) is the speed at which energy is consumed (or generated). Watts (W) - You can watch more videos using Viewtron AI security cameras here. Learn more Ohm’s Law electrical formulas and see more conversions on our Ohm’s Law calculator. Power(W) = (24 V)2 ÷ 12 Ω The Watt (Watts) refer to the “real power” , while the volt-amperes (VA) refer to “apparent power “. 1 watt is defined as the energy consumption rate of one joule per second. Example 2: To convert watts to amps for a 12V DC 500mA power supply, enter 12 volts and .5 amps. It also shows in a simple way step by step how to perform the conversion . Differences, definition and what the VA and Watts are used for. This calculator is only meant to convert the volt amps to watts and therefore alternating the values may give you wrong results. Terms of Use | Adding 3 to the power in dBm is the same as multiplying the power in Watts by two (actually 1.995 but that's near enough for most practical purposes) +10 : X 10: Adding 10 the the power in dBm is exactly the same as multiplying the power in Watts by 10 Volt-amps (VA) to watts (W) conversion calculator. Privacy Policy | For example a 24VAC50 power supply is 24 volt, 50 volt-amps (watts are also known as volt-amps). You can view more details on each measurement unit: mA or watt/volt The SI base unit for electric current is the ampere. Rta: // Only the VA must be multiplied by the power factor , as follows: 2800VAx0.91, the result will be: 2548 Watts. A clothes dryer has a power of 2800VA and a power factor of 0.91 , how much power in Watts does the dryer consume? These apps support live security camera viewing as well as recorded video surveillance playback from remotely over the Internet. Power(W) = 24 watts. These values ​​are useful if you have to eliminate the heat generated by the device that consumes the watts or if you want to know how much you will pay your utility company for using your equipment, since it pays per kilowatt-hour (energy used for a period of time ). Legacy systems can be found around 0.8 and the latest uninterruptible power supplies tend to be released to the market with output standards of 1 where the same UPS will deliver similar values ​​of Watts and VA. As an example, a device with a nominal power of 525 Watts (watts) and a power factor of 0.7 results in a load of 750 VA. It is always preferable that you obtain the value of the power factor with the equipment catalogs. Calculate button to get the voltage in volts: The voltage V in volts (V) is equal to the power P in watts (W), divided by the current I in amps (A): The RMS voltage V in volts (V) is equal to the power P in The user interface is so simple to use. Once you get the VA and the power factor of the equipment (s), you only have to replace these values ​​in the following formula: A refrigerator has a power of 1200VA on its nameplate with a power factor of 0.9 . The RMS voltage V in volts (V) is equal to the power P in watts (W), divided by the power factor PF times the phase current I in amps (A):. The energy in watts consumed is related to the resistance in an electrical circuit. It’s also possible to convert volts to watts if you know the resistance of the circuit. power factor PF times the phase current I in amps The watt [W] to volt ampere [V*A] conversion table and conversion steps are also listed. Rta: // As the formula indicates, you must multiply the VA by the freezer power factor , as follows: 5000VAx0.89 = 4450Watts. Click Calculate. Here is one example of how this calculator is commonly used by security system installers as an amp calculator. Power(W) = 1,620 watts. $99.99 $ 99. Larger UPSs tend to be rated with a higher output power factor of at least 0.9. To correctly size equipment such as UPS, transformers , power plants etc, it is important to understand the relationship between Watts or Watts and VA. Terms of Use | Watt’s Law states that current is equal to power divided by voltage. resistance. You must obtain the VA of the load you want to convert to Watts , for this you can go to the nameplate or catalogs of the equipment (s) , you can also perform an Internet search with the reference of the equipment (s), commonly the power of these electrical devices They come in watts , however there are some inductive loads that have motors and a load assignment in VA. Find the power factor of the equipment for which you want to convert the power of VA to Watts. Click Calculate. power factor PF times the phase current I in amps (A): The line to line RMS voltage VL-L in volts (V) is equal to the power To improve understanding, some examples are made and a table with the main equivalences of VA to Watts is presented. Click Calculate. Conversion Volt-ampere to Watt. The real power (measured in watts) is the portion of power consumed in a machine . The values ​​required to perform the conversion are only 2 (VA and FP) , these two values ​​can be obtained from the nameplates or by measuring with specialized equipment, such as multimeters or power meters, however you can also obtain estimated values ​​of the Power factor  here , these values ​​are reference because each particular equipment will have a different value. 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.
