Greetings Fellow Members;
I've tried to find the answer to this without success, although I know it's out there somewhere...
I have a small, spare back-up UPS that generates a PWM / simulated sinewave. I'm going to connect several vintage digital clocks that use the A/C line to keep time to this UPS since the clocks don't have battery back-up.
Do clocks that keep time based on the A/C frequency require a 'pure' sinewave, or can they run OK on a PWM / simulated sine wave as the clock signal?
Thanks,
William
