Siemens PSX-12M — Cerberus PRO Modular power supply extender, 12 A at 24 VDC, without a battery charger.
The PSX-12M is a high-current auxiliary power supply that expands the main PSC-12M power supply and battery charger with additional 24 VDC power. It is an addressable, microprocessor-controlled module that reports its status to the FCM2041-U3 operator interface, including terminal loading and ground fault information, and it shares the system 60-pin power/data bus with the other cards and modules. Up to three PSX-12M extenders can be connected to one PSC-12M.

FAQ
Does the PSX-12M charge batteries?
No. It is a power supply extender only; the PSC-12M main power supply has the built-in charger for up to 100 Ah lead-acid batteries.
How many can be added to one system?
Up to three PSX-12M extenders can be connected to one PSC-12M.
What AC input does it accept?
It is a universal power supply accepting 120 to 240 VAC at 50/60 Hz, drawing up to 3.5 A at 120 VAC.
Is another filter assembly needed?
One PSFA serves the PSC-12M and one PSX-12M. A second PSFA must be ordered when more than one PSX-12M is used.
