Newmar Phase 3 Modular Battery Chargers

Recognizing that today's complex electronics devices are subject to finite service lives and random failures, and given that modern vessels are increasingly dependent on their electronics and electrical systems for safe operation, Newmar has introduced the Phase Three Modular (PTM) Battery Chargers.

The PTM charger provides a significant improvement in system reliability and serviceability 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 is considered “fault tolerant”.

The system consists of a wall mount case which serves as connection point to AC input and battery output (3 bank). It contains three front-facing power bays, each accommodating a 33.5A (@12V) or 22.5A (@24V) charger module which slides and locks in place creating 100A/12V or 67A/24V chargers.
If a module fault occurs, a front panel indicator and alarm relay is 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 at 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.

• Provides flexibility, reliability, field serviceability - eliminates or diminishes down-time
• 3 redundant, independent, charger modules - a malfunction of one does not disable the charging system; remaining modules continue to operate (at a partially reduced charger output)
• Field serviceable - all system connections are made to the case housing, the charger modules simply plug into bays in the case; no need to touch any wiring
• Three stage "smart" charging - bulk, absorption, float - for rapid, complete charging
• Battery type selector switch; gel-cell, lead-acid, AGM
• Temperature compensated output option
• Numerous diagnostic and system status indicators
• "Universal" voltage input of 90 - 264V AC, 50 - 60 Hz - can be used anywhere in the world
• Battery capacity @ 12V: 80 - 400 Ah per installed module (240 - 1200 Ah per system)
• Battery capacity @ 24V: 40 - 200 Ah per installed module (120 - 600 Ah per system)
• Powder-coated stainless steel case: 20.9"H x 10.9"W x 8.8"D
• Weight: Case = 16 lb, Modules = 6 lb each
• ABS approved as redundant power system for essential services as well as a battery charger
• CE Mark, UL Recognized; E183223, Level 3
• Safety: EN60950-1 USA, Canada, Europe EMI Radiated and Conducted: FCC Part 15 Level A; EN55022 Class A
