retain the existing value. Setting the VREF value to 0V, the module will enter to standby mode. To enable
again the module, set VREF to an acceptable range.
During group module change of output voltage:
 All modules in the group will adjust based on the commanded output voltage.
 OVP is temporarily disabled until the output voltage level reaches the commanded VREF.
 UVP is temporarily disabled until the output voltage level reaches the commanded VREF.
 IREF will automatically readjust if the voltage request is above the nominal output voltage. This will
prevent module to operate above the rated power.
4.4.3.1.1 DVS Parallel Connection Protection
Each individual module in a group will protect independently. Each individual module in a group will protect as
stated on section 4.4.1.1.
4.4.3.2 DVS Series Connection
All modules connected in series should:
 be grouped as one using ISOCOMM WebTool.
 have the same module configuration.
 have the terminals connected in series.
 have each module’s “REMOTE_SENSE_+” connected to its own positive output terminal.
 have each module’s “REMOTE_SENSE_-” connected to its own negative output terminal.
 connect external reverse biased anti-parallel diode to each module output.
Table 4-18 list recommend diodes for each module.
