In 50 VA the V stands for volts and the A is for amps.
Hence the formula you are looking for is 50/240 = Amps.
50 VA means about 50 watts. Transformers usually use VA instead of watts because a transformer has very little wasted power, and watts measure power. A 50 va transformer that is 120v. on the primary side will use about .41 amps at 120 volts. On the secondary side, (if it's 24 volts) it will support about 2.08 amps.
no
There are zero amps in 50 watts. The equation for amperage is, I W/E. Amps = Watts / Volts. As you can see if there is no voltage stated the amperage can not be calculated.
On the 24vac side, this would include any load attached or powered by the transformer. A wire than has gone to ground (shorted), or rubbed into the ductwork (stat wire). The transformer will be rated at xxva, meaning volts X amps aka(watts). Most residential equip. will have a 40va fitted. 40 / 24= 1.66 amps. Any load in excess of this should cause a failure. If you are trying to fix this yourself, put a 2amp automotive fuse in series with one of the 24vac "out" leads and go one by one, isolating the gas valve, wiring to the thermostat, etc, till the fuse quits blowing. Otherwise, call a tech. lc
500mA = 500 miliamper 1000mA = 1 amp so 500mA = .5 amps
To calculate the amperage, divide the VA (volt-amps) by the voltage. In this case, 4.8VA divided by 24V = 0.2 Amps.
The device here that draws 50va is drawing 4.1666 Amps at 12 volts. This is calculated as 50/12. If you're trying to measure the current draw at the mains, then that draw is 50/240, or .208 Amps.
1.3 amps
50 milliamps (mA) is equal to 0.05 amps.
15 Amps
25 A = 25,000 mA
830 milliamps is equal to 0.83 amps.
Yes, 24VAC and a 24 volt power supply are generally compatible, as they both provide 24 volts of power. However, it's important to ensure that the load being connected can accept AC voltage if you're using 24VAC.
25mA is equal to 0.025 amps.
200mAL is equal to 0.2 amps, not 20 or 2 amps. This is because "mAL" stands for milliamps, which is one thousandth of an amp.
24 volts of alternating current
A control transformer marked 240V - 24Vac would have a control voltage of 24 volts.
