DBU-3200 is a 3200W single output AC/DC enclosed charger in 1U low profile with high power density,

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.
