Example 3 : 1.5 slot D4 module with voltages combined.
2 x D4 modules can be combined to provide 36V nominal at 18Amps.

D4 is a single module and the combination will have a bussbar fitted at manufacture to combine the voltages (see
pictures below).
The module description would become 36DD4 ("DD" indicates that two modules are configured to sum the output
voltages).
The suffix "F" for faston or "S" for screw can be added eg 36DD4F or 36DD4S.
Example 4 : 2 slot D5 module with voltages combined.
2 x D5 modules can be combined to provide 48V nominal at 15Amps.

D5 is a 2 slot module and the combination of 2 x D5 modules will have a bussbar fitted at manufacture to combine the
voltages (see pictures).
The module description would become 22DD5 ("DD" indicates that two modules are configured to sum the output
voltages).
Note that in this case, the available output power from the module is greater than the available power the converter
can provide. (48V x 15A = 820W). If this module combination was fitted to a 650W Vega converter, the maximum
available power would be 650W, or 48Vat 13.5Amps.
The suffix "F" for faston or "S" for screw can be added eg 48DD5F or 48DD5S.
