Inquiry (采购产品): Ferroresonant Transformers I was browsing your website and I wanted to clarify something about your Ferroresonant Transformers. Are these devices able to take low DC input voltages and convert them to the standard wall specs, 120v @60 HZ. What disadvantages do these devices have and how expensive are these particular devices? **** Hidden Message ***** Noah Myers 96814 USA Company: Kapiolani Community College E-mail: tigerice45@gmail.com **** Hidden Message ***** tigerice45@gmail.com
