Description
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.

Specifications

Modification for charger specification may be required for different battery specification. Please contact battery vendor and MEAN WELL for details.
All parameters INO specially mentone0 are measured at 250VAG INPput, raled ioad and 25 of amDient temperaure.

Derating may be needed under low input voltages. Please checK the derating curve for more details.
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’90omm metal plate with 1mm of thickness. The final equipment must be re-confimed that it still meets EMC directives. For guidance on how to perform these EMC tests, please reter to “EMI testing of component power supplies.as available on http://www.meanwell.com)

The ambient temperature derating of 3.5 C/100m with fanless models and of

5 C/1000m with fan models for operating atitude higher than 2000m(6500ft). Product Liability Disclaimer For detailed information. please refer to https://www.meanwell.com/serviceDisclaimer.aspx FUNCTION MANUAL

PMBus Communication Interface
DBU-3200 supports PMBus Rev. 1.1 with maximum 100KHz bus speed, allowing information reading, status monitoring. output trimming, etc. For detailk please refer to the Installation Manual.

Charging Curve
By factory default, this charger performs the default curve which can be programmed via PMBus. To disable/ enable the charging curve, change to a 2 stage curve, a different curve frequently used for certain types of batteries in the industry, and so on, please refer to the Installation Manual. To program the parameters of the charging curve, SBP-001, the smart battery charging programmer designed by MEAN WELL, and a personal comniiter are needed please contact MEAN WELL for details

Note:
When using this charger unit, please configured the system with recommended battery capacity defined by specification. Should battery capacity in use be much smaller so that user needs to set a low current for charging, under such condition it might cause higher current ripple.

output Voltage Programming (or, PVI remote voltage programming/remote adjust / margin programming/ dynamic voltage trim) In addition to the adjustment via the built-in potentiometer, the output voltage can be trimmed by applying EXTERNAL VOLTAGE.

Output Current Programming (or, PCI remote current programming dynamic current trim) The output current can be trimmed to 20-100% of the rated current by applying EXTERNAL VOLTAGE.

Remote ON-OFF Control
The power supply can be turned ON/OFF individually or along with other units in parallel by using the “Remote ON-OFF function.

Temperature Compens

Current Sharing
DBU-3200 has the built-in active current sharing function and can be connected in parallel, up to 2 units, to provide higher output power as exhibited below The power supplies to be paralleled should use short and large diameter wiring and then connected to the load. Difference of output voltages among parallel units should be less than 0.2V. The total output current must not exceed the value calculated by the following equation: Maximum output current at parallel operation=(Rated current per unit) X(Number of unit) X 0.9 K When the total output current is less than 5% of the total rated current, or say (5% of Rated current per unit) X(Number of unit) the current shared among units may notbe balanced.
