Description
DBR-3200 is a 3200W single output AC/DC front-end 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.

| NOTE | 1. Modification for charger specificaion may be required for different battery specificaion. 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 aboLt maximum charging current limitation. 4. Derating may be needed under low input voltages. Please check the derating curve for more detais. 5. The charger is considered a component which will be installed into a final equipment. Al the EMC tests are been exected by mourting the unit on a 00mm”900mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it il meets EMC directives. For guidance on how to perform these EMC tests, pi 6.

- PMBus Communication Interface
DBR-3200 supports PMBus Rev. 1.1 with maximum 100KHz bus speed, allowing information reading, status monitoring, output trimming, etc. For detals, 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 a2 stage curve, a different curve frequently used for certain types of batteries in the industry, and soon, please refer to the Installation Manual.
Toprogram 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.

When using this charger unit, please configured the system with recommended battery capacity defined by specification. Should battery capacily in use be much smaller sothat user needs to seta low current for charging, under such condition it might cause higher current ripple - Remote ON-OFF Control
The charger can be turned ON/OFF individually or along with other units in parallel by using the “Remote ON-OFF” function.
Between Remole ON-OFF and +5V-AUX Charger Status Switch Short oN Suitch Open OFF - Output Voltage Programming (or, PV / remote voltage programming / remote adjust / margin programming / dynamic voltage trim)
In addtion to the adjustment via the built-in potentiometer, the output voltage can be trimmed to 75~125% of the nominal voltage by applying EXTERNAL VOLTAGE.
- Output Current Programming (or, PC / remote current programming / dynamic current trim)
The output current can be trimmed to 20~100% ofthe rated current by applying EXTERNAL VOLTAGE.
- Temperature Compensation

To exploit the temperature compensation function, please attach the temperature sensor, NTC, to the battery or the battery’s vicinty.
The charger s able to work normally withoutthe NTC.

LED Status Indicators
| LED | Description |
| Float (stage 3) | |
| Charging (stage 1 or stage 2) | |
| The LED will present a constant red light when the abnormal status (OTP, OLP, fan fail and charging timeout) arises. | |
| The LED will flash with the red light when the internal temperature reaches 60°C; under this condition, the unit still operates normally without entering OTP. (In the meantime, an alarm signal will be sent out through the PMBus interface.) |
