MEAN WELL NPB-450 Intelligent Battery Chargers
MEAN WELL NPB-450 Intelligent Battery Chargers are miniaturized and versatile chargers designed with automatic battery voltage detection technology. These chargers include Near-Field Communication (NFC) to set up charging parameters and select 2/3 stage charging. The NPB-450 chargers include built-in CANBus protocol for the remote setting of charging curves and monitoring charger status. The DIP S.W. on the front panel allows the user to manually adjust the 2/3 stage charging and select between the four types of preset charging curves. The NPB-450 chargers offer protection against short circuits, overvoltage, over-temperature, and battery reverse connection.
The NPB-450 chargers feature a thermal-controlled DC fan for noise reduction, remote ON/OFF control, and <1mA typical leakage current from the battery. These battery chargers also feature 20% RH to 95% RH working humidity (non-condensing), 47Hz to 63Hz frequency range, and automatic power reduction for charging during overheating. The NPB-450 chargers are certified by CB, UL, DEKRA, CE, and UKCA. These chargers are used in AGV, robotic lawn mowers, surveillance systems, washing robots, E-bikes, and telecommunication base stations.
