Frequently we gets requests to provide a transformer or a UPS for a certain piece of equipment. For many reasons, manufacturers tend to be very curt with the electrical or UPS requirements on their brochures. What information they do provide can be cyptic.
Notice, there is NO 220volt in this country. Its a commonly used term to describe the average high voltage power, but it does not exist in nature.
