Details

Meanwell NPB-450-48 is a miniaturized versatile and ultra-wide voltage intelligent charger with 57.6V55.2V42-80V6.8A456.96W24-80AH. It utilizes a fully digital control design with automatic battery voltage detection technology, highlighting intelligent, versatile, user friendly, safe, and compact. Meanwhile, the charging voltage range is wide enough to cover a variety of different battery voltages and battery chemistries. There is also a built-in intelligent voltage detection charging mode (Note this mode is set to OFF by factory default and is suitable for lithium batteries with BMS only). NPB-450-48 can pair with SBP-001 programmer for digital configuration such as adjust charging voltage/current, and set charging cycle time to protect battery lifetime. Furthermore, CANBus communication protocol is built in to meet professional applications, which allows remote controlling and monitoring for the status of the charger. In terms of safety, NPB-450-48 has intelligent detection for proper battery voltage and connection as well as protection from reverse polarity. The product passes ITE IEC/EN/UL62368-1 and household appliances EN60335-1/-2-29 dual safety and 3-year warranty to guarantee reliable operation. In light of its longevity, good quality, and high reliability, Meanwell NPB-450-48 is truly an intelligent, safe, and reliable universal charger with outstanding cost performance.
