24 VAC 40VA Transformer
This high quality AC adaptor is useful for many applications. In most applications, you can use an adaptor with a higher capacity. However, always select an adaptor with the same voltage. Specifications: *Power output: 24 VAC, 1660 mA *Maximum power output: 39.8W *Input requirements: 120 VAC, 60 Hz *Power consumption: 45W *Power output terminals *UL approved. Note: Output voltages are rated at full load. No load voltages can be up to 50% higher.

24 VAC 40VA Transformer
24 VAC 40VA Transformer is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Works as advertisedI bought several of these units to power security cameras in my residence via Ethernet cabling. After doing some googling, I learned that over long wire runs the voltage drop could be sufficiently severe to affect the quality of the video feed from the camera. And well.. enter this power adapter.I connected this to a digital voltage reader to ensure it delivered rated voltage; the meter read 24.5 VAC.I used this adapter with a separately-purchased 24-to-12 volt converter to the security camera and it all works perfect.

Rated 4 out of 5 by from good power sourcebought it for my indoor wall fountain as a replacement for the power soruce that was lost in moving. the adapter works very well. The water in the fountain is more vigerous!

24 VAC 40VA Transformer

Is this a regulated supply?

Although the description states no-load voltages may be 50% higher, the first reviewer states he measured 24.5v. As a novice it wasn't clear if the measurement was taken with load or no-load.
Asked by: rstek
nah, this is just a transformer in a usable package. It does nothing two pieces of wire wrapped around a chunk of iron wouldn't do. =)That said, good transformers are said to have good "load regulation", that is the voltage isn't affected much by the load. Also, it is possible to get a "constant voltage transformer' that uses a L-C resonnant circuit to maintain a voltage level. These are extremely sensitive to the line frequency and the power company has warned that they're in the mood to start jacking around with the frequency, mainly because they feel like it, breaking everyone's synchronous clocks and various other equipment where a frequency of 60.0000Hz (maintained by an atomic clock, with adjustments for leap-seconds etc...) was a design assumption. =\
