As a very rough rule of thumb, the wattage rating of a UPS is approximately 0.6 * its VA rating so, as you have seen, a 700VA UPS is good for a
READ MOREBecause UPS systems are rated by VA or kVA ratings, this may require a conversion from W to VA, which can be calculated by dividing the power consumption (W) by the power factor. Add up all the VA, then multiply this by a figure such as 1.2 or 1.25, which factors in future growth and system expansion. That figure is the maximum size in VA or

READ MORE1. You are right. UPS needs to mention both VA ratings as well as wattage ratings. From a white paper published by Schneider: It mentions that industry standard is to assume watt ratings as 60 % of VA ratings. In your case, you found it to be 70 %. Share.

Just as the table shows below, if Phase A is loaded to 95%, Phase B to 60% and Phase C to only 25%, the UPS will still have 40 kVA, or 36 kW, unused. Therefore, if the actual load required is 90
READ MOREto distinguish between these measures. Background. The power drawn by computing equipment is expressed in watts or volt-amps (VA). The power in watts is the real power drawn by the equipment. Volt-amps are called the "apparent. power" and are the product of the voltage applied to the equipment times the current drawn.
READ MORETaken together, the equation for determining the correct kilowatt requirements of your system looks like: Total Watts = Volts * Amps * Power Factor. In a perfect world, a 1kVA UPS is rated to handle 1,000 volt-amperes, and therefore 1,000 watts. However, no UPS system is 100% efficient, hence the importance of the power factor.
