MEAN WELL NPB Series Ultra-Wide Intelligent Battery Chargers
Product Features
- Ultra-Wide Charging Range: Features a massive 2:1 ultra-wide output voltage range, allowing a single charger to accommodate multiple battery configurations (e.g., 10.5V~21V for the 12V model).
- Intelligent Auto-Ranging: Built-in patented auto-ranging battery detection automatically adjusts charging voltage according to the connected battery's requirements.
- Smart Programming & NFC: Charging curves (2-stage or 3-stage) are selectable via DIP switch. Custom parameters can be set via CANBus, the SBP-001 programmer, or wirelessly via smartphone APP on select NFC models.
- Universal Compatibility: Perfect for Lead-Acid (AGM, Gel, Flooded) and Lithium-ion (LiFePO4, Li-Mn) battery chemistries.
- Advanced Protections: Highly robust design includes protections against Short circuit, Over voltage, Over temperature, and Battery Reverse Polarity.
- Intelligent Control: Includes remote ON/OFF control, temperature compensation (via NTC), and multi-colored LED status indicators.
