40 VA is the apparent power of the load. It is simply the applied voltage multiplied by the resulting current in amperes. Given the VA and the Volts merely divide the VA by the volts to get I=VA/A = 40VA/24V= 1.667 Amperes rms.

How many watts does a 24V - 40VA transformer put out?

A 24V - 40VA transformer can output up to 40 watts. The "VA" (volt-amperes) rating indicates the apparent power, which in this case is equivalent to the real power in watts for resistive loads. Therefore, at 24 volts, it can deliver a maximum current of approximately 1.67 amps (40 VA / 24 V).


What IS power factor on 40VA 24VAC?

There is insufficient information in the question to answer it. You need some other information, such as voltage to current phase angle, inductance, capacitance, or watts. Please restate the question.


What is 40va?

It is 40 volt-amps, which is 40 volts at 1 amp, or 10 volts at 4 amps, etc. On an AC supply it could be equal also to 40 watts, or some lesser number of watts depending on the power factor of the load.


Can 24v 40va be used for24v 1 amp?

Yes, a 24V 40VA transformer can be used for a device that requires 24V 1A. The VA rating (volt-ampere) is a measure of the overall capacity of the transformer to deliver power, so the 40VA transformer has the capacity to supply the 1A required by the device.


What is the max secondary amperage for a 40VA 240x24 volt control transformer?

The secondary amperage for a 40VA control transformer with a 240V primary and 24V secondary voltage can be calculated using the formula Amps = VA / Voltage. In this case, the max secondary amperage would be 1.67A (40VA / 24V).
