3200W Rack Mountable Front End Battery Charger DBR-3200 Series

Description

Mean Well DBR-3200 Series Overview

The Mean Well DBR-3200 Series is a 3200W single-output AC/DC front-end battery charger designed with a 1U low-profile form factor and an impressive power density of 37W/inch³.

This intelligent 3-stage charger comes pre-loaded with programmable charging curves that support a wide range of lead-acid and lithium-ion batteries. It is the perfect solution for charging systems, backup power, and constant current source applications.

With its output programmable function, users can easily adjust both charging voltage and current using either the built-in potentiometer or the PMBus communication protocol.

The DBR-3200 Series also features comprehensive protection mechanisms, including:

Over-voltage protection
Over-temperature protection
Short-circuit protection
Temperature compensation for enhanced safety and reliability.

Thanks to its rack-mountable design, this series is ideal for centralized power management systems and industrial battery charging solutions.
