MERLIN II Release 3 Reusable Modules
The following modules used in a MERLIN II Release 3 system can be used in
this system:
391A1 power supply
NOTE:
While the 391A power supply can be reused in the system, it does not
supply as much power as the 391 Al power supply module and should
be replaced if anything is added to the station side of the system. The
391 A also has less protection against power surges than the 391 A1.
