I have a countdown timer switch with preset time (5 Minutes, 10 Minutes, 30 Minutes. etc) that is used for bathroom fan, lights etc.
127 Volts, 60Hz, 1800 Watts.

Question: how can I make it work using 230 Volts, 60Hz? without using step down transformer but using normal 2 hot lines.

thanks

 

If its only rated for 120v then that is what you will need to supply it, do you have a neutral available ?
If so you could incorporate a relay to switch the 240v.
Max.

You can't.

Since you're using 60Hz, are you in North America?

yes I'm in North America.
I need it for an experiment.

 

Use the timer you have (with one Line and one Neutral) to control a relay with a 120 V coil and contacts rated for 240 V.

Thank you AK.

but what if I want to replace one or more of the components. which one will it be?

 

R1-C2-D1 are the input network that handle the high voltage.
