12/28/2023 0 Comments Wattage temperature conversion![]() Typically, electronic products display one or both of these values to provide information on the amount of energy they will consume or the amount of current they will consume. Each of these values can be used for various purposes. The Watt (Watts) refer to the “real power” , while the volt-amperes (VA) refer to “apparent power “. □Differences, definition and what the VA and Watts are used for.īoth watts (Watts) and volts-amps (VA) are units of measurement of electrical energy. This table shows the commercial values of some UPS with power factors equal to 0.8: VA This becomes even more important as the charges increase in size. Larger UPSs tend to be rated with a higher output power factor of at least 0.9. 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. This allows UPS manufacturers to offer a 300W UPS that can deliver 500VA, which appears to be a much more robust equipment than it actually is. This practice is becoming less common, so it is so important to verify the Watts and VA of a UPS. In many uninterruptible power supplies below 2000 VA, it is common to find a power factor less than 1.0 and, in many cases, as low as 0.6 for smaller systems. Note: It can not be converted from wat to dc watts, because the VA power only applies to AC currents □Table of VA to Watts for UPS (Power factor of 0.8): ![]() 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. 1000va to watts converterġ000 VA equals 800Watts, with a power factor of 0.8 and using the formula: 1000VAx0.8 = 800Watts. Assuming a power factor of 0.8 the result would be 400Watts. To convert 500 VA to Watts you must have the power factor. Table of equivalences from watts to watts for systems that have a power factor equal to 0.8. Rta: // As the formula indicates, you must multiply the VA by the freezer power factor , as follows: 5000VAx0.89 = 4450Watts. Rta: // You must multiply the variables as indicated by the formula VAxF.p , resulting in: 500 × 0.92 = 460 Watts Example 3, conversion from going to watts for a freezerĪ freezer has a power of 5000VA and a power factor of 0.89 , how much power in Watts will the freezer have? Example 2, how much power a computer has in wattsĪ computer has a power of 500VA and a power factor of 0.92 , what is the power in Watts of the computer? Rta: // Only the VA must be multiplied by the power factor , as follows: 2800VAx0.91, the result will be: 2548 Watts. ☝How to convert from VA to WattsĪ clothes dryer has a power of 2800VA and a power factor of 0.91 , how much power in Watts does the dryer consume? It is always preferable that you obtain the value of the power factor with the equipment catalogs. 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 formula to perform the conversion comprises three variables (VA, Watts and power factor) , which are related in the previous formula. Fp = The power factor, is a value of each team, however there are some tables with reference power factors.VA = VoltAmpere (S), own value of each equipment, commonly are powers of the UPS, Transformers, motors, air conditioners, elevators and inductive equipment that have motors.Watts = Active power (P) or watts, this is the value to be found.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.Ĭommonly the power factor can be obtained by performing a search on the Internet with the references of the equipment , however another way is to use a table with common power factors .
