Newmar Ptms-24-67 Charger System

PTMS-24-67 Charger System

The PTM charger provides a significant improvement in system reliability by utilizing multiple independent charger modules that plug into the unit, and should a fault occur in one module, the system continues to operate, thus being considered a “fault”.

The system consists of a wall-mount case that serves as a connection point to AC input and battery output (3 banks) and contains three front-facing power bays, each accommodating a 22.5-amp charger module that slides and locks in place, creating a 24V, 67-amp charger. If a module fault occurs, a front panel indicator and alarm relay are activated, and the system continues operating on the other modules. A fourth bay houses the “smart” controller circuit that provides 3-step charging, temperature compensation, system status LEDs, alarm contacts, and indicators. Should the controller suffer a fault, the charger will still operate at full power in float voltage mode. The controller module is also configured for easy plug-in replacement in the field.

Vessel operators appreciate this system approach to reliability and serviceability, whereby 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, all the while the charging system and the vessel continue to operate.

Reliability

Redundant, independent 22.5 amp charger modules increase reliability; a malfunction of one does not disable the charging system; the remaining modules continue to operate.

Serviceability:

Module change-out takes only minutes via plug-and-play configuration while the system continues to operate
Technical personnel not required
No need to remove the charger case from the boat or disconnect any wiring
No inconvenience of power interruption to the boat
