48V Special Feature: Battery chargers that utilize step charging methods, active in robots, communication systems, and industrial equipment.
Even when transitioning from a DC12V / DC24V system to a DC48V system, there is no need to reassemble the system as the dimensions and weight remain unchanged. Furthermore, heat generation is reduced due to increased efficiency and lower current values (A). Additionally, the four models NPB-120 / 240 / 360 / 450 / 750 have also obtained PSE certification, allowing for safer and more secure use.
