6.4 Rectifier Module
Figure 50 shows the Cordex 48-1.8kW can be used in the AMS24 HP systems to provide battery charging
thumbscrew latch that secures the rectifier into the shelf. During normal operation the rectifier is
locked into position. A handle (or grip) is incorporated into the front panel to facilitate the removal of
the rectifier from the shelf. No special tools are required.

Rectifier status summary
The three LEDs on the front panel show the rectifier alarm, communication fail, and rectifier on/off
status.
AC ON The top green LED illuminates when the AC input voltage is within its allowable range. The LED flashes
(~2Hz) when input voltage is outside the allowable range. The AC input voltage is invalid if the AC Mains
Low or AC Mains High alarm is active. The LED extinguishes if the AC input fails.
DC ON The middle green LED illuminates when the rectifier is delivering power to the load. The LED flashes
when communication is lost. The LED extinguishes when the rectifier is off, e.g., when commanded by
the CXC.
ALARM The bottom red LED illuminates during an active Module Fail alarm if the module is unable to source
power as a result of any of the following conditions:
Output fuse blown AC mains input fail Module fail (ramp test fail)
High voltage (OVP) shutdown Thermal shutdown Local shutdown
UPF fail No output power Fan fail
