420W charger 13.8V/25A, with NFC programming

Intelligent Chargeurs with wide charging voltage range with NFC programming

The NPB-450 series is equipped with intelligent charge management. The wide voltage range makes it possible to use the Chargeurs for different battery types and technologies. For lithium cells with BMS, the charger recognizes 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 device).

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

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