What Does Va Mean On A UPS?

Is Va the same as Watts?

Watts is the real power drawn by the equipment, while volt-amps are called the “apparent power” and are the product of the voltage applied to the equipment times the current drawn by the equipment.


What does 1500va mean?

max instaneous output power1500VA indicates the UPS unit’s max instaneous output power. It means Volts x Amps, and there is no Hours implied in it. The specification “1500VA” does not tell you how long it will drive the load. It does tell you the biggest load it can drive for some brief time.

What does 500va mean?

It is simply the product of volts times amps giving a value of volt-amps, VA, as the answer. Example: You have a transformer that supplies a voltage of 100 volts AC and is capable of supplying a current up to a maximum of 5 amps.

How do you convert VA to Watts?

The formula is VA = Watts / PF (or Watts x PF = VA). Some examples: A 100-watt laptop charger with a power factor of 0.7 would require 100 / 0.7, or 143 VA. Incandescent lights and toasters have a PF of nearly 1, so their VA and watt rating are equal.

How is VA calculated?

VA = VRMS x IRMS (4) You can calculate the apparent power in volt-amperes for ac circuits by multiplying the measured RMS voltage times the measured RMS current.

Can a UPS run a TV?

A UPS is very easy to use. … When the electricity goes off, your computer (or TV, DSTV, light, etc.) will be powered by the battery in the UPS. Surge protection. Note: Manufacturer warranties DO NOT cover damage caused by power spikes!

How do I know what UPS to buy?

You will need to find the UPS capacity. Capacity is how much power a UPS system can provide (measured in Watts). The higher the capacity, the more electronic equipment, and devices it can support. To find the UPS capacity, you will need to calculate the load.

How much Va do I need in a UPS?

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 power load of around (0.6 * 700) = 420W (your specs said 405W). Conversely, the minimum VA rating you need is approximately 1.6 * load wattage.

How long will a 1500va ups last?

A UPS with a 1500VA rating can keep a computer running for less than an hour. You’re lucky if you get more than 10 minutes of run time when running a PC, a networking gear, and a monitor. So generally, you can use your UPS as a backup power supply for not very long.

How long will a 650va ups last?

The battery in that unit has 77 volt amp hours, meaning it’ll last about seven minutes under its maximum rated load (which comes to 390w.) So you should easily be able to last five minutes and some change on paper.

How many watts is 1kVA?

This means that the formula for watts = volts x amps x power factor. For example, 1kVA UPS from N1C has the capacity to power 900 watts of connected equipment. This means the UPS has a “power factor” of 0.9.

What does 1000va mean on a UPS?

Every UPS comes with a “VA rating” (Voltage-Amps) which tells you how much gear you can connect to it and roughly how long it will keep running after the power is cut. … 6 to convert the VA rating into Watts rating – so a 1000VA UPS is designed to handle roughly a 600-Watt load.

How long will a 1000va 600w ups last?

A 1000VA UPS might be able to power a small office computer for around seven minutes. Make the upgrade to a 10kVA UPS, and you might see this figure jump up to around twenty-sevenminutes. Go too small, on the other hand, and the available time shrinks to just a few minutes or less.

Why is UPS rated in Virginia?

VA is an abbreviation of the electrical term volt-amps, and indicates a capacity of power. For example 240 volts x 12.5 amps = 3000VA. It is used by UPS manufacturers more often than Watts because it makes the UPS sound bigger.

How many watts is 650va?

520 watts1-5 of 5 Answers 650 VA (or about 520 watts, considering a power factor of 0.8) represents the total power available for use. VA is the Volt-ampere rating. This will tell you the capacity of the battery and it’s ability to carry a load during a power outage.

How many watts is 500va?

How many watts is 240 volts? The 240 Volts can be equal to 240 watts if you have a connected electrical load like an incandescent lamp that draws 1 ampere of current.. It can also be equal to 2400 watts if you turned your electric stove that draws 10 amperes of current..

How many watts is 800va?

That would rate it at 480 Watts.

What does 800va mean?

1-3 of 3 Answers. 1500VA: VA = volt-ampere : VA in this case is an indicator of how much potential current the DC (Direct Current) batteries in the UPS are rated for. The load. Also the watt rating indicates the total AC (Alternating Current) amout that the UPS can convert and supply.

What does 30va mean?

Volt-ampereVolt-ampere (VA) is a measurement of power in a direct current ( DC ) electrical circuit. The VA specification is also used in alternating current ( AC ) circuits, but it is less precise in this application, because it represents apparent power , which often differs from true power .

What does 900w mean?

‘W’ is power, which is defined as 1 joule per second. So 900W is 900 Joules per second. So for every second it runs, it uses 900 Joules. What may get confusing is that your electricity bill states things in kWH (kilo watt hours). A kWH is how much ENERGY is used if a 1000W (1kW) appliance is used for 1 hour.
