Details
Meanwell NPP-450-24 is a miniaturized dual-purpose charger and power supply with 28.8V21-42V13.5A6.75-13.5A453.6W300mVp-p. In addition to being used as a three-stage charger for lead-acid batteries, the item could 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 (21～42V). Furthermore, NPP-450-24 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. The product also complies with IEC/EN/UL62368-1 and household EN60335-1/-2-29. Due to its long lifetime, high efficiency, and excellent reliability, Meanwell NPP-450-24 is truly an intelligent, safe, and universal dual-purpose charger and power supply with outstanding cost performance.
