NPB-1200 series chargers from MEAN WELL company


MEAN WELL company has released powerful universal chargers of high reliability NPB-1200 series. The main characteristics of this series of chargers are: intelligent control, wide voltage range, versatile design, flexible functions, safety and durability. The device is equipped with a built-in microcontroller and a patented technology for automatically determining the battery charge level, which automatically adjusts the charge parameters depending on the battery voltage (this mode is only suitable for lithium-ion batteries with BMS).

The series presents three different models for voltage of 12 V (10.5 ~ 21 V), 24 V (21 ~ 42 V) and 48 V (42 ~ 80 V), which are characterized by a wide range of charging voltages of 2:1. Each device can be used for a wide range of batteries and thus can replace several highly specialized devices.

NPB-1200 series chargers can be paired with the SBP-001 charger programmer to connect to a computer to program various parameters, such as selecting 2/3-stage charging, adjusting the charging voltage/current, setting the charger standby time. The parameters of the charger can also be adjusted manually using a tuning resistor located on the front panel (to adjust the charging current in the range of 50 - 100%) and a switch (to select the charging mode).

For more professional integration with applications, the NPB-1200 is equipped with a built-in CANBus protocol, which allows remote configuration and monitoring of the charger. As for the safety functions, the charger determines the battery voltage and whether it is connected correctly before charging.

NPB-1200 series chargers can be used to charge electric vehicles, mobile robots, various mobile devices running on direct current.
