Hello
I have an old digital clock for which I would like to create a power supply. It requires 12v AC at exactly 50Hz, which it uses for timing purposes.
I could just buy an AC to AC 12v mains adapter and plug it into the mains. However it would be nice to also power it from a 12 volt battery.
Please can anyone suggest a simple 12v DC to AC inverter circuit to give 50Hz from my battery pack?
Will maintaining exactly 50Hz from a battery source be difficult, thus making the clock inaccurate for timing?
Many Thanks
