MEAN WELL NPB-1700-48 inteligentná nabíjačka batérií 48V 25A 1700W pre olovené a Li-Ion batérie

High-power intelligent battery charger delivering 1700 W at 48 VDC with a maximum charge current of 25 A. The NPB-1700-48 supports programmable 2/3-stage charging for lead-acid (GEL, flooded, AGM) and Li-ion (LiFePO4, Li-manganese, Li-cobalt) batteries, making it suitable for industrial, telecom, and renewable energy systems.

Advantages

Wide AC input range (90–264 VAC), up to 93.5% efficiency, and forced air cooling ensure reliable operation across diverse environments. Built-in protections include short circuit, over voltage, over temperature, and battery reverse polarity. Remote ON/OFF control and optional CANBus/PMBus communication enable integration into complex systems.

Suitable for

• Lead-acid battery banks (GEL, flooded, AGM)
• Li-ion battery packs (LiFePO4, Li-manganese, Li-cobalt)
