NPB-450 is a miniaturized,versatile, and ultra-wide voltage intelligent charger. It utilizes a fully digital control design with automatic battery voltage detection technology,with five key features including intelligent,versatile, user friendly, safe, and compact. The series have four models with output voltage ranges of 10.5~21V,21~42V, 42~80V, and 54~100V respectively.The charging voltage range of each model is wide enough to cover a variety of different battery voltages and battery chemistries, and there is 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).The NPB-450 can pair with MEAN WELL’s SBP-001 programmer for digital configuration, such as adjust charging voltage/current, and set charging cycle time to protect battery lifetime.Through the user-friendly DIP s.W. on front panel, user may also directly adjust the 2/3 stage charging,current(50~100%), and select between the 4 types of preset charging curves. In addition, a 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, it has intelligent detection for proper battery voltage and connection as well as protection from reverse polarity.It passesITE IEC/EN/UL62368-1 and household appliances EN60335-1/-2-29 dual safety and 3-year warranty to guarantee reliable operation.The NPB-450 is truly an intelligent, safe, and reliable universal charger with outstanding cost performance.
