VA to Watts Formula 3 phase and single phase:
- W = Watts
- VA = VoltioAmperios
- Fp = Power factor
Conversiones mas comunes:
500va to watts:
To convert 500 VA to Watts you must have the power factor. Assuming a power factor of 0.8 the result would be 400Watts. Using the formula: 500VAx0.8 = 400Watts.
1000va to watts converter:
1000 VA equals 800Watts, with a power factor of 0.8 and using the formula: 1000VAx0.8 = 800Watts.
Convert 6 va to watts:
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.
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):
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.
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.
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.
