The SEI PoweRack 96
The PR96 is a premises powering unit that integrates NT1 caging, 48 volt DC power, and battery backup in a single unit for powering ISDN telephones and Lucent P-230 circuit card NT1's or equivalents. The PR96 will house and power up to 48 P-230 NT1's and provide power for up to 96 phones in a multipoint mode. Distribution is accomplished using standard 50 pin amphenol connectors which eliminate the need to use punchdown blocks. All power lines to the terminals and NT1's are protected by solid state thermal fusing. Additional external battery packs can be added at any time for increased standby time. During extended periods of utility outage the batteries are protected from over-discharge by the built-in low voltage detector and disconnect circuit. Remote monitoring is provided by a contact closure that can be interfaced to a remote alarm unit.
All PR series units are mountable either on a wall or on 19" racks. Mounting brackets for 23" or 25" racks may be ordered as options (specify 23RM or 25RM after the model number).
