Intelligent Battery Charger

The NPB and NPP series are MEAN WELL s new generation of high-power'

density smart chargers. The NPB-120/240/360 series adopt a high

efficiency hardware design, allowing the products to operate both

efficiently and stably. The NPB-450/750/1200/1700 series are fully digital

designed products and feature the benefits of miniaturization, high

efficiency and intelligence. Being a high efficiency hardware and

microprocessor power management design, with four charge curve

selection (one programmable and three embedded) and the world's first

invention: auto ranging charge, the chargers have the ability to cope with

various batteries from different brands, such as lead-acid batteries

(flooded, gel and AGM) and li-ion (lithium iron, lithium manganese),

which some may require special charge treatment. Users also can adjust

and modify charge parameters (charge voltage/current, cut-off

voltage/current...etc.) in each charge stage via the built-in CAN bus

interface, some battery protection functions, in addition, may be disabled

through the intelligent communication interface. The whole NPP family is

equipped with both charger and power supply modes. These two modes

can be set freely according to user s demand. In the charger mode, a'

three-stage charging function is provided, and the charging voltage and

current can be adjusted according to different batteries. If it s in the'

power supply mode, it will be able to driver loads. The flexible andgeneral

intelligent design of the NPB and NPP series can provide a perfect

solution for complex battery applications.
