PPS 25 Power System
Cabinet System
Description
PPS 25 modular DC power cabinet systems are
designed to meet rigid telecom applications with
very high reliability and flexibility for future
expansion.
These cabinet power solutions
provide rectification, system management and
power distribution while allowing configurable
solutions within the same cabinet or through the
use of external distribution cabinets. The PPS 25
systems are based on hot-swappable fan-cooled
PMP 25 rectifier modules with constant output
power available at 24V/110A or 48V/50A per
module.
System management is accomplished through
messages and alarms displayed on the system
controller’s (PCS) LCD screen and can also be
TM
displayed remotely via the PC-based PowCom
software package.
