What is 30ma in amps?

Milliampere to Ampere Conversion Table
Milliamperes Amperes
20 mA 0.02 A
30 mA 0.03 A
40 mA 0.04 A
50 mA 0.05 A

How many watts is a mA?

The answer is one Milliampere is equal to 0.001 Watt/Volt.

How do you calculate VA amps?

3 phase VA to amps calculation formula
  1. I(A) = S(VA) / (√3 × VL-L(V) ) So amps are equal to volt-amps divided by the square root of 3 times volts.
  2. amps = VA / (√3 × volts) or.
  3. A = VA / (√3 × V) Example. …
  4. I = 3000VA / (√3 × 110V) = 15.746A. Ampere definition.

Is VA same as watts?

Watts refer to “real power,” while volt-amperes refer to “apparent power.” Both are simply the product of voltage (V) multiplied by amperage (A). Thus, a device drawing 3 amps at 120 volts would be rated at 360 watts or 360 volt-amperes.

What does 8va mean in electricity?

Volt-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 .

How many watts is a VA?

A volt-ampere (VA) is the unit used for the apparent power in an electrical circuit. Volt-amperes are useful only in the context of alternating current (AC) circuits. This tool converts volt-ampere to watts (va to w) and vice versa. 1 volt-ampere = 1 watts.

What is 750 VA in watts?

As an example, a device with a nominal power of 525 Watts (watts) and a power factor of 0.7 results in a load of 750 VA. The sizing of a UPS, transformer or power plant to operate at 75 percent of its capacity results in equipment with a lower rating than what you expected .

What is VA in inverter?

It stands for the Volt ampere rating. It is the voltage and current supplied by the inverter to the equipments. … Hence Power supplied (or VA rating of inverter) = Power requirement ( power consumed by equipments in watts) / Power factor( efficiency).

Why is VA higher than watts?

There is a reason why we need to distinguish between VA and watts and it is efficiency. Watts is the actual power needed to accomplish the job in AC, but the power consumed is the much higher VA. In order to minimize the wasted power, it is necessary to get the VA value as close as possible to the watts value.

How do you calculate VA to watts?

The ratio between the VA (i.e. rms volts time rms amps) and Watts is called the power factor PF. In other words, volt-amps x power factor = watts.

How many watts is 600VA?

So then it enter in account the power factor of your load that we can consider a number as 0.8 (80%) so then o this means 600 x 0.8 = 480 Watts. If you load is specified as 480 Watts with power factor 0.8 it will draw 600VA of your power supply, so the UPS of 600VA is rated for that load.

How long will A 600VA UPS last?

Zebronics 600 va UPS-U725 for Desktop

For devices that consume a high amount of power, this UPS offers a battery backup of around 28 minutes and for low power consuming devices, it can offer a backup for 3 hours continuously.

How do you convert kW to VA?

VA to kW Conversion Formula

Volt-amps are equal to 1,000 times the kilowatts, divided by the power factor. For example, convert 5 kW with an 80% power factor to volt amps.

How do you convert kVAh to kWh?

  1. kVArh.
  2. kWh.
  3. kVAh= √(kWh.

How many watts does A refrigerator use?

The average home refrigerator uses 350-780 watts. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it.

Is VA same as kwh?

kW to VA Conversion Formula

Kilowatts are equal to the volt-amps times the power factor, divided by 1,000. For example, follow this example to convert 45 VA with a power factor of 80% to kilowatts.

How do you convert VA to HP?

How to convert Hp to VA in only 3 step:
  1. Multiply Hp (Horsepower) by 746. Example, if you have 100 hp multiply by 746 and you get 74600.
  2. Multiply the Power factor by the motor efficiency. …
  3. Divide step 1 between step 2, the result will be: 103.611VA ((100×0.746)/(0.9×0.8) = 103.611VA).
