ABSTRACT: GR-151 replaces TR-EOP-000151, Issue 1, May 1985, but contains NO TECHNICAL CHANGES from that original document. It has been issued strictly to conform with the new Telcordia Technologies document format and GR process, and carries a new issue number and date.

This document contains design criteria and information essential for the manufacturer of common use battery charging rectifiers that, in the view of Telcordia, should be met in order meet the needs of a typical service provider. It covers rectifiers intended for use in either plus or minus 24, 48, 130, and 140 volt nominal values for straight battery operation (i.e., no emergency or CEMF cells), and central office environments.

When using GR-151, you may need to refer to GR-63 and certain ANSI standards.
