MEAN WELL NPP-450/750 Battery Chargers & Power Supplies

MEAN WELL NPP-450/750 Battery Chargers and Power Supplies offer a 2-in-1 design that ensures flexibility to switch their operating mode, 63Hz maximum frequency rating, and up to 93% efficiency. The NPP-450/750 series is used as a three-stage charger for lead-acid batteries and can be used as a constant voltage output power supply to drive general loads. The operating mode is designed to be quickly switched by plugging and unplugging a connector from the front panel. In addition, these chargers and supplies combos feature remote ON/OFF control, built-in intelligent fan with variable speed based on temperature to reduce noise and extend fan lifetime, and multiple protections including short circuit, overload, overvoltage, and overtemperature. MEAN WELL NPP-450/750 Battery Chargers and Power Supplies are ideal for radio system backup solutions, electric scooter chargers, surveillance systems, and mechanical and electrical equipment.
