Vertiv / Emerson R48-3500e DC rectifier telecom power supply

This item has never been used but I no longer have the factory box that it came in. Will package with the upmost care to make sure it is not damaged in transit.
The eSure™ R48-3500e high efficiency rectifier is designed to convert standard AC supply voltages into stable nominal 48 VDC voltage that is adjustable to application needs. The R48-3500e is a constant power rectifier designed with the latest patented switchmode technology, using DSP (Digital Signal Processor) functionality for efficient operation.VERTIV™ Power Rectifier, Series: eSure™ Series, Model: R48-3500e, 85 to 305 VAC Input, -42 to -58 VDC Output, 73 A Maximum Current, 45 to 65 Hz, 3500 W Output, Power Factor: 0.99, 96.3 % Efficiency, -40 to 167 deg F Operating, 3.36 in Width, 5.2 in Height, 11.3 in D
