Question: What Does 30va Mean?

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..

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 many watts is 1500va?

The BX1500M uses a 12 Volt 9 Ampere hour battery that means it stores 108 watt/hours of energy.

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 is VA rating on transformer?

Transformers are rated in volt amps (VA). It defines the limit of the magnetizing field inside the transformer. If this limit is exceeded, the transformer goes into saturation and ceases to function properly. This is especially important when the transformer has more than one secondary winding.

What does 20 Va mean?

Volt-AmperesShowing 1-3 of 3 answers. I purchased this transformer because it puts out 24 Volts AC (alternating current) and 20 VA (Volt-Amperes) a.k.a. Watts. To calculate the current (Amperes or Amps), divide 20VA by 24V. 20/24=0.833 Amps or 8330mA (milliamps).

How is VA calculated?

A volt-ampere (SI symbol: V⋅A or V A; also VA) is the unit used for the apparent power in an electrical circuit. The apparent power equals the product of root mean square voltage and root mean square current. … The volt-ampere is dimensionally equivalent to the watt (in SI units, 1 V⋅A = 1 W).

How many amps can a 50 VA transformer handle?

50 VA means that it can supply 50 volt-amps. At 24 V secondary that means it can supply a little over 2 A.

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.

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.

What does 10va mean?

900 va (volt ampere) is the inverter capacity, meaning that it will be able to power your 720 Watts to 900 Watts (depending on their power factors) electrical gadgets. It should be a 12 volt DC system ie single battery operated.

Can I use a 16v transformer on a 10v doorbell?

No, 16v is too high. Most likely it will damage your 10v chime.
