To change Group Module output voltage, the user needs to send below B1h (VREF) command using Group
Device address.
Device Address
Module Command
Data
<Group Number>
B1h
< Data is the Set Voltage>
*Before writing to this command, please ensure that the Group Address Write Protect (10h) is disabled.
The desired output voltage setting should be set to the desired output voltage at the load.
Series Operation DVS “Data” = Total Output Voltage of the Series Module connection.
For example, when setting four modules in series to obtain an output voltage of 80V, the group command B1h
should be set to 80V. Internally ISOCOMM will divide the set voltage by the number of modules and will set
each module to an output voltage of 20V.
The module’s output voltage can be programmed within 5% to 120% of the nominal output voltage. Setting
the VREF beyond the acceptable range, but not to 0V, the module will trigger a Status CML fault and will retain
the existing value. Setting the VREF value to 0V, the module will enter standby mode. To enable the module
again, set VREF to an acceptable range.
During group module change of output voltage:
 All modules in the group will adjust based on the computed output voltage for each module.
 OVP is temporary disabled until the output voltage level increases to the commanded VREF.
 UVP is temporary disabled until the output voltage level decreases to the commanded VREF.
