Organization: NEMA
Publication Date: 1 January 2018
Status: active
Page Count: 42
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.
