This listing includes two used transformers with the model number 430-7101-5 EIA 6-9609 Class 180 H1. These transformers are ideal for use in a variety of industrial settings and can be used for power transformation purposes. The transformers have been previously owned, but are in good working condition and have been maintained properly. Tested working came out of a back up battery charging station which kept computers running during a power outage. You may only need one but you will get two for what other people are charging for one. Shipped fast and safe. Thanks for looking!
