Information about the MEAN WELL NPB-1200-48
The MEAN WELL NPB-1200-48 is a highly reliable, intelligent 1200W battery charger featuring an ultra-wide charging voltage range from 42V to 80V. Designed for demanding applications, it supports both traditional lead-acid battery chemistries (flooded, GEL, AGM) and lithium-ion batteries. Delivering up to 18A of maximum output current, it offers high power density and efficiency for 48V battery systems.
Flexible charging management comes integrated directly into the hardware. Users can select 2-stage or 3-stage charging modes and choose from pre-defined battery profiles using front-panel DIP switches. For advanced setups, custom voltage thresholds, current limits, and charging timeouts can be programmed via the built-in CANBus 2.0B interface or using the optional SBP-001 smart programmer. Additional features include a variable-speed cooling fan, remote control capabilities, NTC temperature compensation, and compliance with dual safety certifications (IEC/EN/UL62368-1 and EN60335-1/-2-29).
