Description

NPP-750 is a miniaturized dual-purpose charger and power supply. ln 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 connector on the front panel. Other features include: ultra-wide voltage output, adjustable voltage via VR on the panel (10.5~21V, 21~42V, 42~80V), adjustable charging current (50~100%), built in intelligent fan with variable speed based on temperature to reduce noise and extend  fan lifetime,  -30~+70° C wide operating temperature, suitability for use in different environments, built-in remote ON/OFF control, compliance  to lEC/EN/UL62368-1  and household EN60335-1/-2-29 dual safety, multiple built-in protections, and 3-year warranty. The NPP-750 is truly an intelligent, safe, and reliable universal dual- purpose charger and power supply with outstanding cost performance.
