2.4 Cordex 48-3.6kW Rectifiers
2.4.1 Rectifier Overview
The CXPS 48-2T system is provisioned for use with the high-density Cordex 48-3.6kW rectifier system. The
system ships complete with two (2) 23” 6-module rectifier shelves installed. Individual 3.6kW (75A) rectifiers are
ordered separately.
NOTE: The two (2) installed 6-module shelves with one CXCM4 (controller) allow for up to eleven (11) 3.6kW modules in
a single 825A system. Distribution and buswork capacity allows for a total system load capacity of up to 1200A
with the installation of an additional rectifier shelf.
2.4.2 Remote Control
All alarming and control of Cordex rectifiers is accomplished with a CXC via a CAN bus. The Cordex rectifier
shelves provide connections for serial communications with other rectifier shelves as well as supervisory and
control panels.

2.4.3.1 LEDs
The front panel LEDs provide:
• Rectifier status summary,
• Rectifier software upgrade in progress indication,
• Locate module pattern.
Rectifier status summary will show the rectifier alarm status, communication fail status and
rectifier on/off status.
AC ON
The top LED (green) is on when AC is within valid range. The LED will flash (twice per second)
when AC is outside the nominal range – AC voltage is invalid if the AC Mains Low or AC
Mains High alarm is active. The LED turns off when AC has failed.
