Test conditions and notes6

1. Modification for charger specification may be required for different battery specification. Please contact battery vendor and MEAN WELL for details.
2. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
3. This is MEAN WELL's suggested range. Please consult your battery manufacturer for their suggestions about maximum charging current limitation.
4. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. The charger is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 600mm*900mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to "EMI testing of component power supplies." (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

What is the Mean Well DBR-3200-24 designed for?

The DBR-3200-24 is a rack mountable front end battery charger rated at 3200W with a 24V output. It is intended for charging, backup or constant current source applications that use a rack architecture or central power management, in a 1U low profile format. Its built-in OR-ing FET and parallel control signals make it suitable for larger multi-unit systems.

What battery types is the DBR-3200-24 compatible with?

This model supports lead-acid batteries including gel, flooded, and AGM types. It also supports Li-ion batteries, specifically lithium iron and lithium manganese chemistries. The unit includes built-in default 3-stage charging curves as well as a programmable curve for broader application flexibility.

What are the main electrical ratings of the DBR-3200-24?

The DBR-3200-24 is rated for 3200W output power at 24V with a default constant current of 110A. It accepts a universal AC input range of 90 to 264VAC, or 127 to 370VDC. The output voltage can be programmed from 75% up to 125% of the nominal output voltage.

Can the DBR-3200-24 be used in rack power systems with multiple units?

Yes, this charger provides DA/DB differential signals for parallel control, and units in parallel can be switched on and off together with the Remote ON-OFF function. It also has a built-in OR-ing FET on the output. Those features make it a practical choice for expandable rack-based power architectures.

What protection features are included in the DBR-3200-24?

The DBR-3200-24 includes over voltage, over temperature and overload protection, plus battery low protection signalled through DC OK. Its over temperature protection shuts down the output voltage and then recovers automatically. Over voltage protection is specified at 31.5V to 37.5V and shuts down the output until the unit is re-powered.

Is the DBR-3200-24 suitable for demanding industrial environments?

This model is designed for operation from -30°C to +70°C, subject to the output derating curve. It uses a built-in fan for forced air cooling, with fan-fail and temperature alarm signalling, and is rated for 10 to 500Hz, 2G vibration. These characteristics make it well suited to industrial settings.

What communications and monitoring interfaces are available on the DBR-3200-24?

The DBR-3200-24 supports the PMBus Rev. 1.1 protocol for information reading, status monitoring and output trimming. A CANBus model is also available. These interface options help it fit into monitored or managed power systems where centralized supervision is important.

What certifications and warranty does the DBR-3200-24 include?

This charger is approved to UL62368-1, CSA C22.2 No. 62368-1, TUV BS EN/EN62368-1, and EAC TP TC 004 safety standards. Its EMC compliance includes EN55032 Class B conducted and Class A radiated emissions, and EN61000-4-2, -4, -6, -8, and -11 immunity. The warranty period is not stated on the spec sheet.
