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.
