Each SPX-CABFIN cabinet requires a separately protected circuit, 120/240 Vac, 60 Hz, single phase, 60 amperes.
The AC power may be installed to an AC load center in the splicing/power end chamber through a separate
pedestal- or pole-mounted power transfer cabinet. When operating the SPX-CABFIN cabinet under emergency
power, the recommended minimum generator capacity is 7.5 kW with 220 Vac, 3-wire output.

DC power for the SPX-CABFIN cabinet is furnished by a modular power supply shelf (rectifier shelf) and a DC
distribution panel. The rectifier shelf provides filtered and regulated DC voltage for powering the cabinet while
maintaining the batteries in a fully charged condition. Rectifier output voltage varies according to battery
temperature, for example, 54.5 Vdc at 77°F (25°C). Three systems are available: the Marconi
®
Vortex 25, Lucent
®
CPS 4000, and Alpha
®
4810.
The power supply shelf (
) consists of an equipment shelf, two A25B50 25-ampere rectifier modules, and
an alarm and control assembly for remote alarms. Separately either rectifier module can provide the required DC
power; two rectifiers provide for reliability and load sharing.
Figure 2.
Modular Power Supply Shelf
The power supply shelf requires nominal 208/240 Vac, 60 Hz input power; maximum power consumption is 3,101
watts. Input power is protected by an internal circuit breaker. Rectifier output power is current limited.
The power supply shelf with the Alarm and Control Assembly, and the DC Distribution Panel are factory installed,
but he rectifier modules are ordered separately and must be field installed.
