Details
Meanwell NPP-450-48 is a miniaturized dual-purpose charger and power supply with 57.6V42-80V6.8A457W456.96W480mVp-p±1.0%±0.5%±0.5%. Apart from being used as a three-stage charger for lead-acid batteries, it 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 (42~80V). At the same time, NPP-450-48 highlights 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 model also complies with IEC/EN/UL62368-1 and household EN60335-1/-2-29. In light of its long lifetime, high efficiency, and excellent reliability, Meanwell NPP-450-48 is truly an intelligent, safe, and universal dual-purpose charger and power supply with outstanding cost performance.
