I would like to use a timer to turn on and off a 220 Volt appliance. With a "mechanical" plug-in timer you have 20 minute granularity. But I would like to have a 1 minute resolution. For example - 1 minute off and 1 minute on. I bought a cheap 10 euro digital timer. I was mislead by the package which said something like : Minimum switching interval: 1 minute. But in fact it meant you can set the timer to turn on at 2 o'clock and 23 minutes and then turn off a minute later. After hours of searching I found something here http://www.aquaponiclynx.com/WordPress/wp-content/uploads/2011/03/ART-DNe_600.jpg It seems it's quite nice - you can actually set the device to turn on for example 1 minute and off 3 minute and so on in a loop. But it works only with 120 V and for such a simple device costs 80 $ while the digital sophisticated one was only 10 E. Does anyone know if such a timer (220V) exists? Thank you.
