Frequently asked questions
What is the price of 220V to 9VAC 2A EI Step-Down Transformer (Single Secondary) in Egypt?
220V to 9VAC 2A EI Step-Down Transformer (Single Secondary) currently costs 180 EGP in Egypt.
Where can I buy 220V to 9VAC 2A EI Step-Down Transformer (Single Secondary) in Egypt?
220V to 9VAC 2A EI Step-Down Transformer (Single Secondary) is available from Microohm. Compare the offers above to find the best price.
Why is the estimated DC about 11.3V?
9V AC RMS is about 12.7V peak. Subtracting roughly 1.4V for two diode drops in a bridge rectifier gives about 11.3V DC at no load, which matches the listing estimate.
Will the DC voltage stay at 11.3V under load?
No. The voltage drops as current increases and depends on the filter capacitor size. Use a suitable capacitor and, if you need a fixed voltage, a regulator.
