PSX-12C 12 Amp Power Supply Extender
INTRODUCTION The SIEMENS Model PSX-12C is a high current power supply extender.The power
supply extender works in conjunction with the PSC-12C power supply to provide an
additional 12A of
regulated 24VDC for
internal or external
system use.
Up to three PSX-12C
modules may be
connected to one
PSC-12C power
supply and one set
of batteries.The
PSX-12C has a
microprocessor-
controlled transfer
circuit that allows it
to switch the system
power to stand-by
batteries during loss
or reduction of the
AC power.
The PSX-12C
incorporates a 18A
circuit breaker on the
battery input.
The PSX-12C communicates directly to the PMI-S to report fault conditions and
allows the PMI-S to query the status of the power supply extender.
The PSX-12C mounts at the back of the enclosure of the system and occupies one
location on the Mounting Plate.
Features The PSX-12C features are as follows:
• Universal AC power input 120VAC-240VAC @ 60Hz / 50Hz
• Off-line Switch Mode Power Converter
• Power Factor Correction
• Total Output power of 12A@24VDC
s

• Two separate power output terminals: one power limited terminal with 4A
max @ 24VDC capacity and one non-power limited terminal with 12A max
@ 24VDC capacity (total not to exceed 12A)
• Both output terminals have current measurement capability
• Auto resettable current protection circuits for overload and short circuit
• Access to CC-5/CC-2 System bus
• Communicates via CAN protocol
OPERATION The PSX-12C occupies one network address in the CAN network and has three func-
tional components: the Controller, the Power Supply Extender and the Interface Board.
The Controller monitors the status of the Power Supply Extender (loss of network
communication, 24VDC terminal overload and the status of the battery). This informa-
tion is relayed to the User Interface, where applicable, and is communicated to the
PMI-S for system reporting. The Controller also allows the PMI-S to query the state of
the power supply extender and its current load and can send a diagnostics command
to the PSX-12C.
The Power Supply Extender has an Off-line switch mode power converter and power
factor correction circuit to improve conductive RF emission at low frequency. It is
designed to take voltage inputs of 120VAC-240VAC at 50Hz/60Hz and has one
resettable circuit breaker that can also be used as a battery power switch.
The Interface Board provides diagnostics LEDs, system connections and the terminal
connections on the PSX-12C.
Terminal Blocks, The PSX-12C has one reset switch, six LEDs, one address switch, one circuit breaker,
two terminal blocks, two terminal connections and two 60 pin flat ribbon connections
as shown in Figure 2.The ribbon cable connectors are used to connect the PSX-12C
with a PSC-12C, additional PSX-12-Cs or a Card Cage (CC-2/CC-5).
A reset switch is located on the top of the front panel. Pushing the reset switch re-
initializes the PSX-12C operation.
The LEDs located at the top left of the module and are defined as follows:
POWER - (Green) Normally ON. When illuminated, indicates
that the PSX-12C is powered from the AC
mains. When flashing, indicates that the
PSX-12C is powered from the battery.
MODULE FAIL - (Yellow) Normally OFF. When illuminated indicates
that the module microprocessor has failed.
CAN FAIL - (Yellow) Normally OFF. When illuminated, indi-
cates that CAN communication with the
PSX-12C has terminated.
HNET FAIL - (Yellow) Normally OFF. Not used for E100
applications

24V 12A FAIL -(Yellow) Normally OFF. When illuminated, indicates
that the 24VDC non-power limited output
has a trouble condition or the PSX-12C
has disconnected the 24VDC output due
to current overload or short circuit.
24V 4A FAIL -(Yellow) Normally OFF. When illuminated, indi-
cates that the 24VDC power limited
output has a trouble condition or the
PSX-12C has disconnected the 24VDC
power output due to current overload or
short circuit.
The terminal blocks of the PSX-12C are defined as follows (refer to
Figure 2):
TB3 24VDC Power Limited OutputTerminal.This terminal
output is limited to 4A. When it is exceeded, it will shut
down, light its associated diagnostics LED and send a

INSTALLATION
Disconnect BATTERY and AC
prior to working on equipment.
The PSX-12C mounts on the
Mounting Plate (CAB-MP).The
Mounting Plate may be located
either “IN” or “OUT” of the
enclosure to perform this
installation procedure. If the
Mounting Plate is located “IN”
the enclosure you will have to
gain access to it by opening the
enclosure Inner and Outer
doors. If the Mounting Plate is
located outside of the enclo-
sure, place it in front of you so
that the word “TOP” is at the
top and away from you.
The PSX-12C can occupy any
position on the mounting plate,
but it should be installed in the
row and position that is located
directly above the PTB to
which it is connected. (Refer to
Figures 3 and 5). When the
PSX-12C is mounted correctly
on the Mounting Plate it will be
flush on the top, bottom, and
right with the Mounting Plate
and the mounting screw holes
of the PSX-12C will align with
the threaded posts.
1. Install four M5 screws in
the threaded posts at the
mounting position. Screw
each of the M5 screws
into the threaded posts 5-6
turns.
2. Place the PSX-12C over
the four screws on the
Mounting Plate and slide it
down or towards you to
rest on the four screws.
(Refer to Figure 4.) When the PSX-12C is in the correct position it will be flush
with the top, bottom and right side of the Mounting Plate.
3. Tighten the four screws.
