MEAN WELL NPB-750-48 750W Programmable Smart Battery Charger 48V 15.6A Lead-Acid/Li-ion

For industrial battery maintenance, the MEAN WELL NPB-750-48 provides 750 W of programmable charging power for 48 V lead-acid and lithium-ion batteries. It operates from a 90–305 VAC input and delivers up to 15.6 A, with adjustable output voltage from 43.2 to 57.6 VDC. The charger supports 2/3-stage charging profiles and is programmable via CANBus or PMBus using the SBP-001 programmer (sold separately). Built-in protections include short circuit, overload, over voltage, over temperature, and battery reverse polarity. The metal case measures 250 x 150 x 50 mm and weighs 2.5 kg, with a built-in DC fan for cooling.
