When using PMBus to adjust output voltage, VOUT_COMMAND only can be used to display the
rated voltage of the unit and cannot be written. It is VOUT_TRIM that sets up the amount of
trimmed voltage. Taking DBU-3200-24 as an example, to get a 18V output, please set value of
VOUT_TRIM to -6V. Adjustable voltage range for each model is shown as below:
The value of CURVE_FV should be set less or equal to CURVE_CV,If CURVE_FV is greater than
CURVE_CV, it will be saved as CURVE_FV = CURVE_CV in EEPROM.
