Details
Meanwell NPP-450 Series is a miniaturized dual-purpose charger and power supply. In addition to being used as a three-stage charger for lead-acid batteries, it can also be used as a constant voltage output power supply to drive general load. The operating mode can be quickly switched by plugging or unplugging a connect or on the front panel (10.5~21V, 21～42V，42~80V，54~100V). At the same time, NPP-450 stands out with ultra-wide voltage output, adjustable voltage, adjustable charging current (50~ 100%), built-in intelligent fan, -30~+70℃ wide operating temperature, and built-in remote ON/OFF control. What’s more, the product complies with IEC/EN/UL62368-1 and household EN60335-1/-2-29. Considering its long lifetime, high efficiency, and excellent reliability, Meanwell NPP-450 Series is truly an intelligent, safe, and universal dual-purpose charger and power supply with outstanding cost performance.
