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.

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.

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

BUT

This now is an offline power discussion, which is forbidden by the terms of service for this forum.
