GE Critical Power NE075AC48ATEZ Infinity Rectifier Features and Advantages Compact - 1RU form factor provides high power density Operates over a broad temperature range 34 Watts / Cubic inch. (40C through +75C). Efficient - Peak efficiency of 95% occurs at 50% load Fail safe performance hot insertion capabilities allow for matching sweet spots with customer use patterns. rectifier replacement without system shutdown soft start and inrush current protection prevent nuisance tripping of Flexibly provides 75 Amps of 48 Volt power from both upstream breakers. conventional and sustainable sources of energy. Extended service life parallel operation with automatic Starts and runs at any AC voltage from 95 to 305 Vac. load sharing ensures that units are not unduly stressed. Uncompromised Advanced A True System Solution Technology to Simplify Your Network Infinity Rectifiers are part of the proven Infinity Power System platform particularly designed to meet the unique GE Energys NE075AC48ATEZ Infinity Single-phase Rectifier is needs of the ever-changing network landscape. designed to efficiently transform energy from any AC source into the 48 Volt DC power needed for Central Office, MTSO and Monitoring / control the built in microprocessor wireless cellular sites. This means that one single rectifier can controls and monitors all critical rectifier functions be used globally to meet all your 48V powering needs. and communicates with the system controller using the built in Galaxy Protocol serial interface. Dual Voltage Compatible - unique connector pin Efficiency is market leading for diode protected, designation allows the 48 Volt rectifiers to be used true hot pluggable, 48 Volt rectifiers. The in a Universal power shelf, alongside DC-DC NE075AC48ATEZ offers a powerful combination of converters supporting loads at 24 Volts dc. efficiency, network simplicity and reliability. Plug and Play installation of the rectifier in a shelf connected to a compatible system Efficiency % Typical at 277V controller initializes all set up parameters automatically. No adjustments are needed. Proportional Load Share when paired with a NE050, both rectifiers share equal amount of load in relation to each units capacity. Meets most 3 phase needs. Works with 208V 3 Phase in a phase to phase configuration. Works from 480V 3 Phase in a line to neutral configuration.Electrical Specifications INPUT VOLTAGE & OUTPUT POWER Response to AC input voltage Operates according to figure, turning on at all V above 90V .
