Progressive Dynamics PD9125-24LV: Precision 25A 24V LiFePO4 Charging

The Progressive Dynamics PD9125-24LV is an industrial-grade power converter and battery charger specifically engineered for 24V Lithium Iron Phosphate (LiFePO4) systems. Part of the renowned Inteli-Power 9100L Series, this 25-Amp charger delivers a filtered DC output that ensures your battery’s internal BMS (Battery Management System) operates with perfect balance and efficiency. Whether for solar energy storage, emergency vehicles, or marine applications, it provides the stable, high-current power required for modern lithium banks.

Built with a dedicated 2-stage lithium charging profile, the PD9125-24LV maximizes battery lifespan by delivering a constant current until the battery reaches its full charge voltage of 28.55V, then automatically tapering to maintain a full state of charge. Its advanced Variable Speed Intelligent Cooling Fan monitors internal temperatures and only activates when necessary, ensuring ultra-quiet operation during low-demand periods.

Key Performance Features:

• Lithium-Specific Charging: Factory-set to 28.55V to meet the exact requirements of LiFePO4 chemistries, ensuring a 100% depth of charge without overstressing cells.
• Total System Protection: Features electronic current limiting, high/low line voltage protection, and automatic thermal shutdown to protect both the charger and your expensive battery bank.
• Reverse Battery Protection: Includes a user-replaceable fuse circuit that protects the unit from damage in the event of accidental cross-connection of battery leads.
• Filtered DC Power: Delivers clean, smooth power that is ideal for sensitive electronics and ensures balancing circuits within the battery operate correctly.
• Scalable Power: The PD9100L series can be wired in parallel to achieve higher charge rates for massive battery arrays.

Technical Specifications:

Installation Tip: Use a 5/32" hex driver to tighten output terminals to 50 in-lbs. The terminals are rated for 2 to 14 GA copper or aluminum wire. Ensure the unit is mounted in a dry, ventilated location to allow the cooling fan to operate efficiently.
