Como Converter VA em WATTS em 5 MINUTOS Mesmo que você NUNCA tenha FEITO essa conta

⚡How to Perform an Electrical Installation Safely, Even if You're Not a Professional Electrician: https://eletr.co/cortes-engehall/?utm... ------ How to Convert VA to WATTS in 5 MINUTES Even if You've NEVER DONE the Math The power consumed by a piece of equipment is expressed in watts or volt-amperes (VA). Wattage is the actual power consumed by the equipment. Volt-amperes are called apparent "predicted" power and are the product of the voltage applied to the equipment times the current drawn by the equipment. Both Watt and VA ratings have a specific use and purpose. The watt rating determines the actual energy purchased from the utility company and the heat load generated by the equipment. The VA rating is used to size wiring and circuit breakers. The wattage value will always be less than or equal to the corresponding VA value due to the "Power Factor" (PF). The Power Factor is a number between 0 and 1 that represents the fraction of the current that provides available energy to the load. Only with purely resistive loads, such as incandescent light bulb filaments like a light bulb, is the power factor equal to 1 (one). For computer-type equipment, the Power Factor to be used should be between 0.6 and 0.7. In other words, the power in watts for computers is a value between 60% and 70% of the value in VA. New power supply technologies are being developed and introduced to the market (called power factor-corrected switching power supplies) that allow for a power factor of 1 or close to 1. A good power factor to use for computers is 0.65. The example below will help you understand the subject: A 1000VA UPS will be able to power a 1000W light bulb, but it will only be able to power a 650W computer. IN THE CASE ABOVE, to convert watts to VA, divide the wattage by 0.65. VA = Watts / 0.65. Some devices will only display the power supply voltage (volts – V) and the current (amps – A). In this case, we'll need to calculate the power, a quick and simple calculation: Power (VA) = Voltage (V) x Current (A) (The result is expressed in VA) For example: A device that uses a 120-volt power supply and consumes 5A will consume: Power = 120×5 = 600VA To convert this value to watts: Watts = 600×0.65 = 390 watts In this case, our system consumes 390 watts or 600VA. Assuming a safety margin of 30% (or higher), we can purchase a UPS with a capacity greater than 507 watts or 780VA.
