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. charger The is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on
600 900 For guidance on how to a mm* mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives.

DBU-3200 supports PMBus Rev. 1.1 with maximum 100KHz bus speed, allowing information reading, status monitoring, output trimming, etc. For details,
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.

Description
The LED will present a constant red light when the abnormal status (OTP, OLP, fan fail and charging timeout) arises.
Red (Flashing) The LED will flash with the red light when the internal temperature reaches 60 ; 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.)(
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.
