Note:
2. When using PMBus to adjust output voltage, VOUT_COMMAND only can be used to display the rated voltage of the unit and
4.Data format of IOUT_OC_FAULT_LIMIT(46h) is as below: (Please refer to PMBus_Specification_Part_II_Rev_1-1 for detailed
information).
3.Insert a at least 35msec delay between commands.
1. READ_IOUT will display ZERO amp when output current is less than the values in the table below.
cannot be written. It is VOUT_ TRIM that provides voltage trimming function. Take PH3500-24 as an examples, to get a 12V
output, please set value of VOUT_TRIM to -12V. Adjustable voltage range for each model is shown as below.
