Information About the MEAN WELL NPP-750-48
The MEAN WELL NPP-750-48 establishes a high benchmark as an advanced 2-in-1 multi-purpose unit that seamlessly converts between a 3-stage battery charger and a constant voltage power supply. By simply inserting or removing a jumper connector on the front panel, operators can immediately toggle between operating modes. Delivering 720 Watts of power with an adjustable output voltage range of 42 to 80 Volts and a configurable current range from 6.7 to 13.3 Amps, this unit provides outstanding flexibility for 48V lead-acid battery maintenance (flooded, Gel, AGM) as well as direct industrial DC loads.
Engineered for high-demand environments, the NPP-750-48 features a wide operating temperature envelope spanning -30 °C to +70 °C alongside a superior energy efficiency rating of up to 93%. A built-in smart thermal-controlled DC fan automatically adjusts its speed according to internal temperatures, effectively lowering acoustic noise and extending fan longevity. The power supply also integrates essential control capabilities such as Remote ON-OFF control, TTL status output signals for DC OK / Charger OK, and full electronic protection against short circuit, overload, over voltage, and over temperature. Backed by dual safety compliance across IEC/EN/UL62368-1 and EN60335-1/-2-29 standards, it is reinforced with a dependable 3-year manufacturer warranty.
