MEAN WELL DBR-3200 & DBU-3200 Battery Chargers
MEAN WELL DBR-3200 and DBU-3200 Battery Chargers are 3.2kW single-output AC/DC smart chargers available in a rack or enclosed type. These chargers feature a 1U low profile and high power density of up to 37W/in3. The modules are fully digitalized and include pre-loaded programmable charging curves for different types of lead-acid and Li-ion batteries. These chargers provide design flexibility with built-in functions such as programmable output (PV and PC), active current sharing, and remote on-off control. A programmable output function allows users to adjust the charging voltage and current via the built-in potentiometer or power management bus (PMBus) protocol.
MEAN WELL DBR-3200 and DBU-3200 Battery Chargers provide various protection mechanisms and temperature compensation functions for a normal and safe system operation. These chargers also include auxiliary power and built-in in ORing FETs to support hot swap (DBR-3200). Typical applications include industrial automation, telecommunication equipment, battery charging equipment, and electrical vehicle (EV) charging stations.
