AC/DC Smart Charger With Low Profile and High Power Density



The DBR/DBU-3200 is a 3.2KW single output rack-type/enclosed type AC/DC smart charger in 1U low profile and with high power density up to 37W/inch3. This series operates at 90-264Vac & 120-370Vdc input voltage and offers models with the DC output mostly demanded by the industry. Each model is cooled by a thermostatically controlled fan. Moreover, DBR/DBU-3200 provides vast design flexibility by equipping various built-in functions such as a 3-stage programmable charging curve, programmable output (PV & PC), active current sharing, remote ON-OFF control, auxiliary power, built-in ORing FETs to support hot swap (DBR-3200), etc.
It contributes to MEAN WELL’s first fully digitalized PSU series, and a digitized PSU design further improves switching efficiency, power density, reliability, and also makes possible programmable tuning on electrical parameters and internal control and human machine interface (HMI). System-wise, power management is feasible by using digital controller and PMBus or CANBus communication protocols to realize synchronous monitoring on input and output parameters. Step by step, the goal of intelligent power supply is therefore achieved in the long run. This series is suitable for applications in industrial automation, telecommunication equipment, battery charging equipment and EV charging stations that requires power source capable of high output (10KW and beyond).
