1.4 Electrical Safety
WARNING!
WARNING!
WARNING!
• Before working with any live battery or power system, follow these precautions:
a. Remove all metallic jewelry, such as watches, rings, metal rimmed glasses, or necklaces.
b. Wear safety glasses with side shields at all times during the installation.
c. Use OSHA approved insulated hand tools.
Lethal voltages are present within the power system. Always assume that an electrical
connection or conductor is energized. Check the circuit with a voltmeter with respect to
the grounded portion of the enclosure (both AC and DC) before performing any installa-
tion or removal procedure.
• Do not work alone under hazardous conditions.
• A licensed electrician is required to install permanently wired equipment. Input voltages can range up to 480 Vac.
Ensure that the utility power is disconnected and locked out before performing any installation or removal proce-
dure.
• Ensure that no liquids or wet clothes come into contact with internal components.
• Hazardous electrically live parts inside this unit are energized from the batteries even when the AC input power is
disconnected.
Follow battery manufacturer’s safety recommendations when working around battery
systems. Do not smoke or introduce an open ame when batteries (especially vented
batteries) are charging. When charging, batteries vent hydrogen gas, which can ex-
plode.
• Batteries are hazardous to the environment and should be disposed at a recycling facility. Consult the battery
manufacturer for recommended local authorized recyclers.
Hazardous voltages are present at the input of power systems. The DC output from rec-
tiers and batteries, though not dangerous in voltage, has a high short-circuit current
capacity that may cause severe burns and electrical arcing.
WARNING!
High leakage current, earth connection essential before connecting the supply.

2. Introduction
2.1 Scope of the Manual
This manual covers the features and installation of the Alpha Technologies CXPS-E101 series 100A and 225A 48Vdc
power systems.
In addition to this manual, the following documents may be included in the documentation package that ships with
the CXPS-E101:
• 0350058-J0 Cordex HP Controller Software Manual
2.2 Product Overview
The CXPS-E101 series power systems are complete integrated 48Vdc power systems available in either 100A or
225A capacities. Each system uses the advanced Cordex CXCM1 controller and HP 48V 1.2kW rectifier modules.
The CXDM-E1 1RU 225A distribution panel provides front access for DC distribution circuit breakers.
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 accepts a wide range of input voltages, allowing the flex-
ibility to connect to supply mains rated 120/208/220/230/240/277 Vac, 50/60 Hz. The system has de-rated output
below 176Vac input. See specifications in the next section.
The 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. Rectifier modules are not included with the base system, but may be
purchased along with the system at the time of ordering, or added after the shelf has been installed. The shelf rectifier
system includes the Alpha Cordex CXCM1 modular controller.
This system uses the controller modular version, which is factory installed on the Cordex rectifier system shelf.
The CXCM1 controller allows the user to configure, monitor and control the entire DC power system locally or re-
motely via a web browser. Features of the unit include temperature compensation, auto equalization, remote access,
e-mail alarm notification, battery diagnostics, as well as web server and SNMP support for configuration and monitor-
ing.
Details of the controller operation are provided in the software manual.

The CXC illuminates the LED that corresponds to the alarm status. Only one LED is illuminated at a time during alarm
conditions:
• Green: OK, no alarms present
• Yellow: Minor alarm is present (no major alarms)
• Red: Major alarm is present
Progress and Status Indication
The LEDs are also used in the following situations:
• Base unit validation: All three LEDs on simultaneously
• File transfer: Red LED illuminates when recovering from invalid firmware application
• Lamp Test: All three LEDs flash in sync for two seconds
4.2.4 Reset
A reset button is located on the front panel for restarting the controller. During reset, the controller may occasionally
need to run a defragmentation cycle. This can be recognized by the LEDs cycling on the front panel. A full defrag-
mentation may take up to 20 minutes to perform, do not power down the controller during this time.

cable.
4.2.6 Analog Input Channels
The controller is provided with analog input channels for voltage, current, and temperature.
Voltage Inputs
Two voltage input channels, V1 and V2, provide monitoring of discharge and charge voltage. The CXC software is
preconfigured to monitor V1 for battery voltage and V2 for load voltage.
V2 is wired internally to the rectifier shelf to provide a reference for rectifier float voltage, low voltage disconnect (LVD),
system high voltage alarm, and system low voltage alarm.
Wire V1 to battery to monitor battery voltage or change battery setting from V1 to V2 in Signals > Configure Sig-
nals.
Current Inputs
The CXC software is pre-configured to monitor I1 for battery current, wired internally to the battery current shunt.
Temperature Inputs
Two temperature input channels, T1 and T2, provide monitoring of battery temperature and temperature compensa-
tion (temp comp) or room/ambient temperature.
4.2.7 Digital Input Channels
The controller can accommodate up to two channels and can monitor digital alarm/control signals from rectifiers,
converters and many other types of equipment.
4.2.8 Alarm and Control Output Relays
The controller contains four Form C digital alarm output relays to extend alarms and control external apparatus.
Each internally generated alarm or control signal may be mapped to any one of the relays, or, several signals may be
mapped to just one relay or none at all.
4.2.9 Network Connection and Remote Communication
The Cordex system can be set up, monitored and tested via an Ethernet connection. The communication protocol
supports a web interface. All alarming and control of Cordex rectifiers is accomplished with a CXC via a CAN bus.
A step-by-step connection wizard – provided to establish remote communications with your CXC – is available via the
Alpha website (http://www.alpha.ca/downloads).

4.4 Cordex CXRF-HP Rectifier
The Cordex CXRF-HP series of 48V 1.2kW rectifier modules employ high frequency, switch mode technology featur-
ing high power conversion efficiency. All internal semiconductor devices operate under “soft-switching” conditions
and exhibit very low power loss. The reduced power loss leads to lower thermal stress on the semiconductors and
thus improves reliability.
Sustaining low component temperatures is again the primary factor with meeting the three worst-case field scenarios:
(1) 65°C ambient temperatures, (2) full output power, and (3) low AC input (176Vac). While meeting these specifica-
tions, Cordex rectifiers also offer roughly twice the reliability at 55°C and up to four times more at 45°C ambient
temperature.

4.4.2 LEDs
The front panel LEDs provide rectifier status summary and help to locate a specific module with the controller.
AC
The top LED (green) is on when AC is within valid range and the rectifier is delivering power to the load. 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 (or no AC power is present).
DC
The middle LED (green) is on when the rectifier is delivering power to the load. The LED turns off when the rectifier is
off; e.g., when commanded via the controller.
Alarm
The bottom LED (red) is on continuously in the event of an active Module Fail alarm. The LED flashes (~2Hz) when a
minor alarm is detected. The LED remains off in the absence of an alarm. If the unit output is not connected to a bat-
tery or parallel rectifier, the LED extinguishes if no AC power is present.
LED Activity During “Locate Module” Command from Controller
When the “locate module” command has been received from the controller, the LEDs behave in a distinctly different
way so that the rectifier is easier to visually identify among adjacent rectifiers.
This state is entered when commanded via the controller. The LEDs flash in a distinct pattern repeating every two
seconds.
LED Activity During Firmware Upload
When a rectifier firmware upload is in progress, the LEDs behave in the same way as the locate module command
described above.

A locking clip automatically secures the rectifier into the shelf.
4.4.4 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.
4.4.5
NOTE:
For Cordex rectier 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 controller. Refer to the soft-
ware manual for detailed information.
Heat Dissipation
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.
4.4.6 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
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.
4.4.7 Wide AC Range
A minor alarm is generated when the AC input voltage drops below specification.
• Output power is reduced linearly between 176Vac and 132Vac to 60% of the rated output power.
• Input current is limited to less than 6A for operation from 132Vac to 90Vac. Power is derated linearly between
132Vac (~700W) to 90Vac (~475W).
• At a lower voltage the module will shut down and will not restart until the AC is greater than 90Vac.
• For voltages above 277Vac, power factor and total harmonic distortion may be derated. Up to 320Vac, the recti-
fier may not be operational but shall not suffer any damage.
4.4.8 AC Inrush/Transient Suppression
An external surge suppressor is not required at the AC input, modules are protected from input lightning and transient
surges in accordance with IEEE/ANSI C62.41 Category B3.
4.4.9 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.
1 Under 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.
