DESCRIPTION
The PS/BC rectifier is part of the Total Access Rackmount AC Power Supply/Backup Battery
System (APS/BBS). The unit is designed to work in conjunction with one or two ADTRAN
backup battery packs (P/N 1175044L1).
Originally designed for the Total Access 1500 system, the PS/BC can be used in any appli-
cation using 120 VAC input, and requiring up to –54 VDC, 6-amps output.
In the Total Access 1500 configuration, the rectifier performs AC to DC conversion and when
used with the dual battery provides up to eight hours of backup power for a fully populated
Total Access 1500 bank (96 FXS circuits) with up to 50 percent off-hook circuits at any one
time.
For general use, the rectifier receives AC power from a standard 120 VAC wall outlet and
converts this to –54 VDC, 6-amp output to the designated load plus recharging the single or
dual battery, or maintaining battery at peak charge. Each battery has four series connected
12 volt rechargeable cells.
Single or Dual Battery
Each battery string is rated for 3 amps of current and 7 amp-hours of capacity. Dual batteries
are required if the load exceeds these ratings during AC power failure (backup battery mode).
PS/BC Mounting Location
The PS/BC normally mounts to the associated battery pack. The unit can also mount to a
special bracket within a cabinet, or mount external to a cabinet against a wall.
