Description
DBR-3200 series
3200W Rack Mountable Front End Battery Charger
DBR-3200 is a 3200W single output AC/DC front-end charger in 1U low profile with high power density, 37W/inch3 . 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.
