1 Introduction
1.1 Scope of the Manual
This instruction manual explains the installation, interconnection, and operation of Alpha Technologies’ Cordex
24-3.1kW modular switched mode rectifier system.
NOTE: To aid the user with installation, frequent reference is made to drawings located at the rear of the manual.
1.2 Product Overview
A complete Cordex rectifier system consists of one or more power modules in a common shelf enclosure. The
shelf has connections for AC inputs, DC output, and system communications.
Cordex rectifier modules use a high frequency, switched mode conversion technique to provide a fully regulated
and isolated DC output from the AC mains. The rectifier input is wide range to allow use on 208/220/240Vac
50/60Hz electrical service.
Rectifier power modules are “hot swappable” meaning they can be inserted or removed from the shelf without
cutting power to or from the system or the load.
Additional power modules can be included with the system at the time of ordering or added after the shelf has
been installed.
The shelf rectifier system is designed to operate with the Alpha Cordex System Controller (CXC).
The CXC allows the user to configure, monitor and control the entire DC power system from its touch screen
display similar to that used in a Personal Digital Assistant (PDA). Other features of the unit include temperature
compensation, auto equalization, remote access, dial out on alarm, battery diagnostics, as well as Web server
and SNMP support for configuration and monitoring.
Details of controller operation are provided in the current version software manual.
There are two external CXC models of the system controller that communicate with the shelf via offset RJ-12
shelf connectors. The CXCR is mounted in a rack and the CXCP is (factory) mounted in a panel.
The CXCM4 is a 4 RU model designed for integrated use with the rectifier shelf; requires a connection interface
(adapter) for modular installation and uses the shelf space of the leftmost rectifier position (as viewed from the
front). This CXC model also has a touch screen display.
Features and details for wiring are provided in the respective chapters of this documentation package.

2 Rectifier Features
2.1 Front Panel
Figure 2–Cordex 24-3.1kW modular switched mode rectifier (shown with optional charcoal finish)
2.1.1 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.
2.1.1.1 AC ON
The top LED (green) is on when AC is within valid range. The LED will flash (~2Hz) 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.
2.1.1.2 DC ON
The middle LED (green) is on when the rectifier is delivering power to the load. The LED will
flash when communication is lost. The LED turns off when the rectifier is off; e.g., when
commanded via the CXC.
2.1.1.3 ALARM
The bottom LED (red) is on continuously in the event of 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 (1 and 2) fail.
The LED will flash (~2Hz) when a minor alarm is detected; if the modules output capability has
been reduced or a minor component failure is detected during the following conditions:
VAC meter fail
AC foldback
Remote equalize
Fan (1 or 2) fail
Low output voltage
High output voltage
Current limit (programmable option)
Power limit (programmable option)
High temperature foldback
Temperature sense fail
Soft start operation
Communications lost.

The LED remains off in the absence of an alarm. If the unit output is not connected to a battery
or parallel rectifier, the LED will extinguish if no AC power is present.
2.1.1.4 LED Activity During Software Upload
When a rectifier software upload is in progress, the LEDs will behave in a distinctly different way
to indicate new rectifier software is being transferred from the CXC.
When a rectifier data transfer is in progress, all three LEDs will flash in a sequence lasting 1.5
seconds. When the last LED is lit, the sequence is repeated beginning at the first LED.
2.1.1.5 LED Activity During ‘Locate Module’ Command from CXC
When the ‘locate module’ command has been received from the CXC, the LEDs will behave in
another distinct fashion so that the rectifier is easier to visually identify among adjacent
rectifiers.
This state is entered when commanded via the CXC. The LEDs will flash in a ping-pong pattern
repeating every 2 seconds.
The ping-pong pattern lights each LED sequentially. After the last LED is lit, each LED is lit in
reverse sequence. When the first LED is lit, the pattern repeats. The effect makes it appear as if
the light is bouncing between the first and last LED.
2.1.2 Mechanical
A thumbscrew is provided to secure the rectifier into the shelf. During normal operation the rectifier shall be
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.
2.2 Rear Panel
Located on the rear panel of the rectifier is a single connector for shelf power and communications.
2.3 True Module Fail Alarm
The power modules have a “true” fail alarm. This provides a true indication of the power module’s ability to source
current. When the module’s output current drops below 2.5% of the rated output a low output current condition is
detected and the Module Fail detection circuit is activated. This circuit momentarily ramps up the output voltage to
determine if the module will source current. If no increase in current is detected, the Module Fail alarm is
activated. The module will test once every 60 seconds for the condition until current is detected. Output voltage
ramping will cease upon detection of current1. A minimum 2.5% load is required to avoid the Ramp Test Fail
alarm; this can typically be provided with the parallel system battery. Activation of this alarm could indicate a failed
module or a failed load.
NOTE: For Cordex rectifier systems without batteries (or with a very light load; below 2.5% of rated output) it is
recommended that the ramp test be disabled to avoid nuisance alarms. The Ramp Test feature is
enabled/disabled via the CXC menu item: Rectifiers, Configure Settings.
2.4 Heat Dissipation
Each rectifier module is equipped with at least one front-mounted fan. The fan operates at temperatures above
0°C (32°F). Cooling of the module is front-to-rear with the exhaust air exiting at the back. The fan is variable
speed; which is determined by heatsink temperature and load.
2.5 Over Temperature Protection
Each rectifier module is protected in the event of an excessive increase in temperature due to component failure
or cooling airflow blockage. During over temperature conditions, the rectifier limits the output power as well as the
1Under normal conditions, a battery connected to the output of the rectifier will draw current when the voltage ramp occurs. Therefore the rectifier fail
alarm will not be generated with a battery connected.

output current. If temperature continues to increase, a shutdown of the rectifier is initiated. The rectifier shall
restart automatically if the temperature has returned to a safe level.
2.6 Wide AC Range
A minor alarm is generated when the AC input voltage drops below specification. Rectifier output power is
reduced linearly between 176Vac and 150Vac to 75% of the rated output power (the unit will deliver derated
output power down to 80Vac).
At 80Vac, the module will shut down and will not restart until the AC is greater than or equal to 150Vac; however,
the restart voltage depends on the load current. At reduced load current the unit may restart with the input voltage
as low as 100Vac.
For voltages above 277Vac, power factor and total harmonic distortion may be derated. Up to 320Vac, the
rectifier will be operational and shall not suffer any damage.
2.7 AC Inrush/Transient Suppression
The inrush current of the rectifier module is limited to the full load steady state line current to prevent surge on the
AC line. Modules are also protected from input lightning and transient surges in accordance with IEEE/ANSI
C62.41 Category B3.
2.8 Soft Start
To eliminate an instantaneous demand on the AC source, a soft start feature is employed. Soft Start, sometimes
referred to as “current walk-in”, works by gradually (up to five seconds) ramping the current limit up from zero to
the actual or defined customer setting. The rectifier output voltage is ramped up from the minimum voltage to the
float voltage.
2.9 Start Delay
The rectifier modules are equipped with a delay timer in order to stagger start a series of modules to prevent
excessive loading of generators upon start up. The built-in timer delays the turn on of the module depending on
the value selected (up to 120 seconds) via the CXC. A minimum one-second delay is preset to allow charging of
the input capacitors.
2.10 Current Limit/Short Circuit Protection
The current limit function determines the maximum output current limit of the rectifier module, regardless of output
voltage or power. Maximum output current is limited to a constant value down to short circuit condition. Current
limiting can be used to mate the rectifier output current ampacity to the needs of the load and parallel battery to
minimize excessive battery recharge current.
The rectifier will sustain a short circuit at the output terminals indefinitely. The maximum short circuit current shall
not exceed 105% of the rated full load current.
2.11 Power Limiting
Each rectifier module is designed to limit power output to the module specification. This enables more current to
be supplied at lower output voltages, and allows matching of output to the demand of constant power loads,
normally seen with telecom equipment.
This feature may also be used for a faster recharge of flooded batteries paralleled with the load.
NOTE: Current limiting overrides the power-limiting feature.
2.12 High Voltage Shutdown (HVSD)
This feature provides protection to the load from over voltage conditions originating from the rectifiers. It operates
by shutting down the offending rectifier module when a high output voltage condition occurs. Indication is through
the red Alarm (Module Fail) LED. Modules will restart automatically; however, if more than three over voltage
conditions occur in one minute, the module will latch off and remain shut down until it is reset via the CXC.

2.13 Battery Eliminator Operation
Rectifier modules maintain all specifications (except where indicated) with or without a battery attached in parallel
to the output; however, if a battery or another module supplying DC voltage in parallel is not present, there will be
no monitoring or control activity if there is an AC power failure or input fuse failure.

3 CXCM4 Features
The CXCM4 (Cordex Controller, Modular, 4RU) is mounted in the rectifier system shelf and brings advanced
monitoring technology to the Cordex series of rectifiers. This compact system controller is designed for seamless
operation and set up of Alpha power systems and is equipped with the complete range of Cordex software
features, including the following:
•Designed to communicate directly with Cordex rectifiers
•Includes battery temperature compensation charging
•Battery performance diagnostics
•Provides local and remote communications
•User definable alarms
•Daily logging of power system events and system statistics.
Behind the CXCM4’s front panel lies the main controller motherboard, which contains a microprocessor, memory,
as well as numerous other electronic components.
The CXCM4 includes a web server providing easy set up and monitoring using an Internet connection with the
standard Windows Internet Explorer browser.
The data logging feature allows the user to capture data from multiple inputs, for AC/DC voltages, load/battery
current, cell voltages & temperatures (automatically for up to 16 user defined logs). Typical applications of the
CXCM4 logging include power system details, thermal performance of outdoor enclosures, battery cell specifics,
or mains variations captured by an AC voltage watchdog.
A built-in audio speaker sounds an intermittent tone during active alarms.
The input/output (I/O) board houses a series of terminal connections; located at the back of the system shelf.
