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
