1.PMBus Communication Interface
2.Charging Curve
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.
◎ Default 3 stage charging curve ◎ Embedded 3 stage charging curves
please refer to the Installation Manual.

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.

◎ 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.◎
