Our source of domestic water is a spring. There is a pump enclosed in a pump house and it operates on 220V. I want to install a filter system that uses a clock (110V) to control backflushing of the limestone filter. My problem is, the power to the pumphouse consists of two hots and a ground, no neutral. What I want to know is, can I use one of those step down transformers to get 110V to operate the clock? As near as I can determine from websites describing the transformers, they are made to be used with 220V european (or elsewhere in the world) power. Those voltages are a single hot with respect to ground while US 220V is what it is, with each hot at 220V with respect to the other hot. Can I use one of these transformers with US 220V input? I can't see much of any other option rather than replacing the wiring to the pumphouse which would be beaucoup expensive (underground wiring) given the distance. Any help is appreciated.
