I am looking for a 240 VAC 50 Hertz electronic timer to turn on and off small electrical units (computer, monitor, etc) during the time I am away from home. I need to acess my network when not at home, but do not want them to run constantly. I need to access my network daily for an hour or so. Does anyone know where I can purchase 2-3 of these timers? There are many available in the USA but are 120 VAC 60 Hertz. I am looking to buy in Thailand. Thanks

Home Pro has them. The sell both digital models with a battery backup and mechanical (analog) models that you need to reset every time the power goes out.

I've also seen the mechanical type at Tesco/Lotus.
