DuganD,
Thank you for your inquiry.
No; The PSU-017 is to be used only with the older DRS2D or DRS4D radar sensors when connecting to any of the TZT or TZT2 series equipment.
The DRS6A does not need a power supply unit when connected to the older MFD12 or MFDBB NavNet3D equipment.
When connecting a DRS6A to any of the current TZT9/14/BB or TZT2 12F/15F/BB equipment, the PSU-012 is required.
The PSU-013 is only required when using the DRS25A.
