Phase Three Modular (PTM) Concept
With the expansion of communication networks to remote
sites and mobile applications where 12VDC
and
24VDC redundant power is essential
for high reliability, there is increasing demand for DC power systems in a wall
mount configuration.
The Phase
Three Modular (PTM) system was specifically designed for
this purpose and provides rack mount power redundancy
features in a wall mount unit and gives installers a
convenient and professional solution for this growing area
of network power.
Recognizing that all equipment has a finite service life and
random component failure can occur at any time, system
reliability can be improved by reducing the number of single
points of failure, thus diminishing the impact of a solitary
fault on the overall system. The PTM series applies the
"fault-tolerant" concept to battery chargers, by using
multiple independent charger modules within the unit.
The PTM
consists of a case which serves as connection point to AC
input and battery bank output, as well as three front-facing
power bays, each accommodating a 550 watt charger module
which slides and locks in place. If a module fault occurs, a
front panel indicator is activated and the system continues
operating on the remaining modules.
Communication system managers will appreciate this system
approach to reliability.
A dead
charger and dead batteries can disable a network, but with
the PTM redundant charging system a fault in one of the
modules is easily identified and it can be quickly replaced
with an on-hand spare or an exchange unit from the factory,
while the charging system continues to operate.
The
system features three stage charging for rapid recharge and
optimal battery life.
