1Introduction
1.1 Scope of the Manual
This manual explains the features, installation and interconnection of the Alpha Technologies CSM56 down converter
module with integrated backup.
1.2 Product Overview
The CSM56 down converter module uses a high frequency switched mode conversion technique to provide a bulk regulated
–50 to –55 Vdc output from multiple isolated ±190 Vdc inputs. This converter is directly compatible with the Alpha CSM36
48 Vdc to ±190 Vdc up converters that are used in network powering applications.
Network (a.k.a. Express, Simplex, Remote, Centralized) powering is a method of distributing energy over an existing copper
network. Multiple twisted-pair copper wire is used to distribute 100 VA limited power sources at ±190 Vdc. The individual
isolated inputs are terminated at a remote end and converted back to a bulk 48 Vdc supply.
Supercapacitors have been incorporated into the CSM56 to provide at least four (4) seconds of backup for a 350 W, 48 Vdc
load.
The CSM56 module slides and plugs into the Lucent Stinger®1
DSLAM cabinet. The module provides external connections
for inputs and output interfaces.

2Converter Module Features
Each module contains five (5) isolated DC to DC converters with a control and supervisory circuit.
Figure 2–CSM56 converter module front panel
2.1 Microcontroller
The microcontroller for each converter monitors both the inputs and outputs of the converters, turns the converters on and
off, and generates a fail status indication if a converter fails.
2.2 Indicators
LED indicators on the front panel display the operational status of the module.
2.2.1 Converter Status
This LED indicator illuminates green when all inputs are present and all converters are functioning normally. It illuminates
yellow if the output voltage is within normal range but one or more inputs, or converters, are not functioning.
The LED will not be on or will illuminate red, or alternate red-yellow, if the output is not within the normal range because
of a circuit failure or overload.
2.2.2 AlphaCap Backup Status
This LED indicator illuminates green when the backup capacitors are fully charged and flashing green when they are
charging.
The LED will alternate green-yellow when supplying backup power. It will alternate green-red when over-charging or if the
charging circuit fails.
The LED will not be on, or will illuminate red if the AlphaCap backup system has failed.
2.3 Test Points
There are current limited meter probe test points for each -53Vdc output on the front panel. For accurate (< 2% error) input
voltage measurements, use a voltmeter set to > 20 MWinput resistance.
2.4 Lock
A captive type screw is used to lock the module into place in the Lucent Stinger® DSLAM cabinet.
2.5 Handle
The front mounted grip (handle) is used for easy insertion and removal of the CSM56.

2.6 DC Inputs
A 10-pin female Tyco mini-fit connector is located on the front panel. It is used to connect five (5) ±190 Vdc input power
pairs, which require customer-supplied overvoltage protectors at the host system.
2.7 Input Low Voltage Lockout
A fault detection circuitry electronically protects the converter module from low input voltages. If the input to any
converter falls below the lower DC input limit, the module will shut down and go into a converter fail mode.
2.8 Input Current Limit
A precision input current limit circuit ensures that the CSM56 converter never overloads a CSM36 or compatible converter
(±190 Vdc 100 VA source with 250 mA minimum output).
2.9 DC Output
A 10-pin blind-mate Molex connector is located on the rear panel and plugs into the Lucent Stinger® DSLAM cabinet for the
–48V and +Gnd output terminals.
2.10 Output Power
Each of the isolated converters on the CSM56 module has a maximum output capacity of 75 W for a total capacity of 375 W
per module. The power output is a function of the input voltage into each converter. Proper network engineering and
copper pair sizing is required to accommodate the power demand of the load.
Input Voltage
Figure 3–Power per converter (x5 per CSM56)
2.11 Over Voltage Protection (OVP)
The OVP feature safeguards the module and load from converter over voltages. If an over voltage is detected from a
converter output, the OVP will shutdown the corresponding converter output. The OVP shutdown level is preset at the
factory. Once an over voltage condition is sensed, the microcontroller for that output will attempt to restart the output
repeatedly.
2.12 Output Current Limit
The current limiting function provides a primary response to output overload situations.
2.13 Regulation and Paralleling
Alpha modular converters use “output slope” or “regulation offset” to accomplish load sharing.
Output Power per Converter in Watts
(maximum module power is double)

Burnaby, British Columbia. Telephone: [phone], Fax: [phone]. Page 4 of 11
2.14 Over Temperature Protection
The converter module is protected against excessive ambient temperatures, restricted cooling air flow, or operation at high
altitudes. Under these conditions the converter will shut down and the converter LED will turn red, flash red-yellow, or
switch off.
At 60°C (140°F) or greater the AlphaCaps may switch off. At 70°C (158°F) or greater a converter may switch off. Normal
outputs will return automatically when the ambient temperature drops below the set point.
2.15 Ventilation
The converter is cooled via natural convection and/or forced air-cooling. The air flows from the bottom to the top of the
housing. To maintain proper operation over the full temperature range, allow at least one rack space above and below the
converter shelf. The airflow baffles should be deflecting any heated air away from the input (bottom) of the converter shelf.
The 4-module shelf uses an integrated fan.
2.16 Paralleling Diode
Individual converters are equipped with a paralleling diode to ensure uninterrupted operation of the system in case one
converter fails.
2.17 Reverse Polarity Operation
The converter design allows reverse polarity operation from the connection to a power source on the input. This prevents
damage to the converter circuitry if a reverse connection is made, and allows the output to continue to be powered.
CAUTION: To optimize safety, wire the shelf with the correct polarity on all inputs.
