I can say that 24VAC means 24 volts alternating current. 24VDC @ 1A means 24 volts direct current delivered at 1 ampere. So the difference I suppose would be: 1. Alternating current VS. Direct current 2. X Amperes(VAC) VS. 1 Ampere (VDC)
yes it is compatible to use 24VAC to 24V supply
24 volts of alternating current
A control transformer marked 240V - 24Vac would have a control voltage of 24 volts.
4.8va/24v = 0.2a
24VAC used to make dual band 12VAC eg. AC sign wave. one is negative goes up, one is positive goes down. polarities switch and frequency is made and can be tuned. Commercial application: Lots of medical equipment. Seismagraphs.
Find a step down 240VAC to 24VAC transformer and connect the 24 VAC output to a full wave bridge rectifier rated for at least 30V. From the DC output of the full-wave bridge you will have 24 VDC. Full wave bridges rectifiers are easy to find at local electronic shops. If you are really adventurous build one out of 4 diodes. There are many plans on the Internet
Transformer turns ratio is the ratio of voltages between two windings. For instance, a 24VAC control transformer that runs on 120VAC will have a turns ratio about 5 to 1.
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.
The manual for your timer should have one. I've also seen them on displays in home centers. They're not that complex. You have a transformer that puts out 24VAC, one wire being hot and the other common. Hot runs to the timer. Common runs to the timer and all the valves. The other lead on each valve goes to an output of the timer. Really, beyond that its instalation specific.
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.
There is no such equation, since the output of a step-down transformer is not DC. The AC output is simply the input voltage divided by the turns ratio. So, if the input voltage is 120V, and the turns ratio is 5:1, then the output would be 24VAC. Now, if the transforner is followed by a rectifier, producing a DC output, then the output voltage depends on the type. For a half-wave rectifier, the DC output is 0.707 time the AC output. For a full-wave rectifier, the DC output will be 1.414 times the AC output. So, if we take our 24VAC transformer output, and feed it through a full-wave rectifier, the DC output would be 33.9VDC. If the rectifier output is smoothed by a filter capacitor, then the above is only true if the power supply is loaded. The half-wave rectifier output will drift up to the peak voltage (1.414 * AC) if it has no load.
Look on the side of the relay case. Here you will find the pin configurations for the C class contacts and the pins that connect to the relays coil to operate the relay.
