How do I get DC from this transformer?
Connect the two 4.5 V outputs to a full-wave bridge rectifier, or to two diodes using the center tap as the common return, then add a filter capacitor. The peak output before diode drop is about 6.4 V (4.5 x 1.414), and the actual DC level will be lower under load.
Is it compatible with Egyptian mains voltage?
The primary is rated for 220 VAC input, which matches Egypt's standard 220 V supply at 50 Hz. Confirm the frequency rating on the unit before connecting it.
