FUNCTION MANUAL.PMBus Communication Interface DBU-300 supports PMBus Rev.. with maximum 00KHz bus speed, allowing information reading, status monitoring, output trimming, etc. For details, 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 stage curve, a different curve frequently used for certain types of batteries in the industry, and so on, please refer to the Installation Manual.

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. 54 55A LED Green Orange Red Red (Flashing) Description Float (stage 3) Charging (stage or stage ) 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 ; 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.) 4. Output Voltage Programming (or, PV / 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.

The charger is able to work normally without the NTC. CN Unit 5 6 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+ (PIN5) and RTH- (PIN6) from each unit still need to be connected. Unit 5 6 8. Alarm Signal Output There are alarm signals, DC OK and T-ALARM, in TTL signal form, on CN. These signals are isolated from output. The maximum sink current is 0mA. PIN5 DC OK PIN6 T-ALARM Application Circuit CN PIN GND-AUX
9.Current Sharing with Remote Sensing DBU-300 has the built-in active current sharing function and can be connected in parallel, up to 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.V. The total output current must not exceed the value calculated by the following equation: Maximum output current at parallel operation=(rated current per unit) (Number of unit) 0.9 When the total output current is less than 5% of the total rated current, or say (5% of Rated current per unit) (Number of unit) the current shared among units may not be balanced.
