Mean Well has expanded its AC/DC charger line by adding the PB-230, a 230W aluminium enclosure battery charger with active PFC function. Along with the existing products PB-120 (120W), PB-300 (300W), PB-360 (360W), PB-600 (600W) and PB-1000 (1000W), the company provides users various choices of metal case battery chargers from 120 to 1000W, with diverse models and charging capacities. Using the standard IEC320-C14 inlet as the input connector, the device features 90 to 264V AC full range input and active PFC function, and hence can comply with harmonic requirement per EN61000-3-2, which has been requested by the European Union. The chargers are suitable for all kinds of batteries such as lead-acid battery, Lithium-Mn (LiMnO2) battery, Lithium-Fe (LiFePO4) battery, and sealed lead-acid gel battery.
The device possesses three-stage charging curve (constant current, constant voltage and floating) and can monitor battery capacity by detecting battery voltage. The device can quickly charge the battery at constant current mode in a low battery capacity status. When the battery bank becomes full, the charger can automatically turn into constant voltage mode with slight charging current to avoid lifetime reduction caused by over-charging. Thereafter, relying on its floating-charge function, the capacity can be sustained at a sufficient level to allow user access any time. Other standard functions include front panel ON/OFF power switch, two-color LED indicator for charging status, remote ON/OFF control, fan speed control, short circuit, over-voltage, and over-temperature protection. These chargers acquired global safety/EMC certificates, which guarantee safety for all different charging applications such as electric motor, electric bicycle, electric wheelchair, security system, leisure vehicle and office/commercial equipment.
