NOTE|

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″C 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 http://www.meanwell.com)
6. The ambient temperature derating of 3.5″C/ 1000m with fan less models and of 5°C /1000m with fan models for operating altitude higher than 2000m(6500ft).

FUNCTION MANUAL

1. PMBus Communication Interface
   DBU-3200 supports PMBus Rev. 1.1 with maximum 1 OOKHz bus speed, allowing information reading, status monitoring, output trimming, etc. For details, please refer to the Installation Manual.

2. Charging Curve
   • By factory default, this charger performs the default curve which can be programmed via PM Bus.
   •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 computer are needed . Please contact MEAN WELL for details.
   • Default 3 stage charging curve
   
   Suitable for lead-acid batteries (flooded, Gel and AGM) and Li -ion batteries (lithium iron and lithium manganese).

Note:
When using this charger un it, 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.

OLP, fan fail and charging timeout) arises.
Red (Flashing)| The LED will flash with the red light when the internal temperature reaches 60°C; under this condit ion , the unit st ill ope rates normally without entering OTP. (In the meantime , an alarm signa l will be sent out through the PMBus interface.)
4. Output Voltage Programming (or, PV / remote voltage programming I remote adjust/ margin programming I dynamic voltage trim)

• In addition to the adjustment via the built-in potentiometer, the output voltage can be trimmed by applying EXTERNAL VOLTAGE.
  
  

  5. Output Current Programming (or, PC/ remote current programming/ dynamic current trim)

• The output current can be trimmed to 20-100% of the rated current by applying EXTERNAL VOLTAGE.
  

  6. 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.

     Switch Short| ON
     Switch Open| OFF
  7. Temperature Compensation
     • To exploit the temperature compensation function , please attach the temperature sensor, NTC, which is enclosed with the charger, to the battery or the battery’s vicinity.
     • The charger is able to work normally without the NTC.
     
     When multiple chargers are connected in parallel, please configure with the NTC as exhibited in the diagram.
     If the temperature compensation is not required, RTH+ (PIN 15) and RTH- (PIN

16. from each unit sti ll need to be connected.
    

8. Alarm Signal Output
   • There are 2 alarm signals, DC OK and T-ALARM , in TTL signal form, on CN1. These signals are isolated from output. The maximum sink current is 10mA.
   

9. 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
   • 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 not be balanced.
