DP140e

The DP140e is a bulk powering system that provides 48 volt DC power for up to 24 NT1's and 48 ISDN phones. Integrated battery backup insures continuous phone service in the event of local power outages. The system controller protects the batteries from over-discharge via a low voltage disconnect circuit. It performs an automatic battery test and indicates when the battery needs to be replaced. The battery is replaceable without taking the phones out of service. Remote monitoring is provided via relay contact closures or SNMP with the optional Power Management Package (PM).

DP140E

Output is provided via a distribution module with one 50-pin Amphenol connector and two 6-pin RJ11 connectors. Each output is indvidually protected from overload via a resettable thermal fuse. Battery holdover can be extended by adding external BP-8U battery packs or High Capacity Battery Cabinets. All DP140e units are mountable either on a wall or on 19" racks.

For applications which do not require battery backup, a no-battery model is available which only requires 7 inches of wall or rack space.
