NPB-450/750 series chargers from MEAN WELL company

MEAN WELL has released an updated series of NPB-450 and NPB-750 chargers to replace the popular PB-600/1000 series chargers that are being discontinued. NPB-450 and NPB-750 are unique universal chargers of high reliability with a capacity of 450 W and 750 W with intelligent control, a wide range of voltage and charge current adjustment. The devices use a patented technology for automatic battery charge detection, which automatically adjusts the voltage and charge current parameters depending on the battery voltage (for lithium-ion batteries with BMS). Models with output voltages of 12 V (10.5~21 V), 24 V (21~42 V), 48 V (42~80 V) and 72 V (54~100 V) can be used to charge a wide range of batteries.

The NPB-450 and NPB-750 series can be paired with the SBP-001 charger programmer to connect to a computer for programming various parameters. The parameters of the charger can also be adjusted manually using the DIP S.W. button on the front panel to set the charging current (50~100%) or select between 4 preset curves.

For more professional integration with applications of the NPB-450/750 series, they are equipped with a built-in CANBus protocol, which allows remote configuration and monitoring of the charger.

Chargers are suitable for charging electric motorcycles, bicycles, scooters, other electric vehicles, mobile robots, hand-held power tools.
