## ■ 

DBR-3200 is a 3200W single output AC/DC front-end charger in 1U low profile with high power density, 3 37W/inch . It is an intelligent charger that has pre-loaded programmable charging curves for different types of lead-acid and li-ion batteries. Output programmable function allows user to adjust the charging voltage and current via the built-in potentiometer or PMBus protocol. Various protection mechanisms as well as the temperature compensation function are provided to assure normal and safe system operation. The rack-mountable attribute fits DBR-3200 perfectly for the charging, backup or constant current source applications exploiting the rack architecture or central power management.

## 3200W Rack Mountable Front End Battery Charger 

## **FUNCTION MANUAL** 

## **1.PMBus Communication Interface** 

- ※ DBR-3200 supports PMBus Rev. 1.1 with maximum 100KHz bus speed, allowing information reading, status monitoring, output trimming, etc. For details, please refer to the Installation Manual. 

## **2.Charging Curve** 

- ※ By factory default, this charger performs the default curve which can be programmed via PMBus. 

- ※ To disable / enable the charging curve, change to a 2 stage curve, a different curve frequently used for certain types of batteries in the industry, and so on, please refer to the Installation Manual. 

- ※ To program the parameters of the charging curve, SBP-001, the smart battery charging programmer designed by MEAN WELL, and a personal computer are needed. Please contact MEAN WELL for details.

## **3. Remote ON-OFF Control** 

The charger can be turned ON/OFF individually or along with other units in parallel by using the "Remote ON-OFF" function.
