3200W Intelligent Single Output Battery Charger DBU-3200 Series

Description

Mean Well DBU-3200 is a 3200W single output AC/DC enclosed 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 DBU-3200-24 is the 24V variant of the DBU-3200 series, specifically designed to provide high-efficiency charging for 24V lead-acid and li-ion battery applications. It features programmable output settings, allowing users to adjust both charging voltage and current to match the specific requirements of their batteries. This ensures optimal performance and helps to extend battery life.

The DBU-3200-48 offers the same high power density and intelligent charging capabilities, but for 48V systems. It also provides programmable output options, allowing precise control over the charging parameters to accommodate 48V lead-acid and li-ion batteries.

Both models are equipped with overvoltage, overcurrent, and temperature protections, along with temperature compensation to adapt to varying environments. They are ideal solutions for industrial and commercial battery charging applications.

In the same Mean Well battery charger family, you may also consider:

The DBR-3200 series programmable power supply, designed for constant voltage or constant current applications with digital control and PMBus communication.
The RCB-1600 series intelligent battery charger, offering a 1600W configurable solution with multiple output options for industrial and medical use.
The RPB-1600 series industrial battery charger, featuring high-efficiency constant current and voltage modes with comprehensive safety protections.

These models complement the DBU-3200 series by offering flexible choices for various system requirements.
