Phase Three Modular
Charger Modules "Plug-and-Play" Providing Fexibility, Reliability & Servicebility in a Wall Mount Case
Phase Three Modular (PTM) Concept
With the expansion of communication networks to remote sites and mobile applications where 12 and 24 volt redundant power is essential for high reliability, there is increasing demand for DC power systems in 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. See our Phase Three Page for a complete description of the three stage charging process.
