420W Battery charger 13.8V/25A NFC programming

Intelligent chargers with wide charging voltage range

The NPB-450 series is equipped with intelligent charging management. The wide voltage range allows the chargers to be used for different battery types and technologies. For lithium cells with BMS, the charger recognises the required charging voltage and automatically starts the charging process with the ideal charging curve (switched off at the factory, can be activated on the unit).

The charging curves can be programmed via NFC. The programming app is available for Android or IOS devices.

For integration into complex systems, a CANBus interface is also available to control and monitor the charger.
