4 Rectifiers
NE050AC48ATEZ
Overview
The NE050AC48ATEZ Series rectifier (50A) operates from single-phase ac
service with a phase-to-phase voltage within the range of 95 to 275Vac.
The rectifiers are shipped separately from the cabinets for quick and
straightforward installation into rectifier shelves at the site.
Interconnections to ac input, dc output, and control signals occur
automatically during insertion. No settings or adjustments to
potentiometers are necessary.
The NE050AC48ATEZ rectifiers are UL Recognized for both the U. S. and
Canada, comply with UL1950 (Information Technology Equipment), and
meet EN60950 requirements.
