Organization: NEMA
Publication Date: 1 January 1997
Status: inactive
Page Count: 47
scope:

This Standards Publication covers stabilized constant-potential-type filtered or unfiltered battery chargers which are designed to supply direct-current power from an alternating-current source to charge a float-type battery and simultaneously power the connected telecommunication system load. These battery chargers provide transformer isolation of the direct-current output from the alternate-current input and are designed for stationary mounting and continuous operation.
