The PR230e is available in two configurations. The PR230-24 will house and power up to 12 P230 NT1's and provide power for up to 24 phones in multipoint mode. the PR230-48 adds additional caging to house and power a total of 24 NT1's with power for 48 multipoint phones. Note that the PR230-24 can be field upgraded to PR230-48 capacity via the 230R NT1 cage.

PR230e output distribution is provided through 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. Dual load-sharing rectifiers offer redundancy, while 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.

The PR230e-24 can be utilized to provide power to third-party NT1 cages such as the Lucent M-210 . Additionally, a stand-alone 230R expansion cage may be powered by legacy powering units such as the Lucent 1145. 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).

When NT1's are purchased with a PoweRack 230e, SEI will install and individually test each NT1, providing the customer with a fully configured solution suitable for immediate installation.
