 DC/DC Converter Module 

User Manual, UM1C48241500 (Revision E, July 20, 2015) 

Spec. No: 1C48241500 

 

Code: UM1C48241500 

Model No: C48/24-1500

Cooling:  Each converter module contains a fan for forced 
convection cooling. 

a.

 

Fan Fault Protection:  The converter module shuts 
down and its alarm indicator (red) flashes if the fan 
fails.  Fan failure is detected and reported to 
controller.  The fan is not field replaceable. 

b.

 

Fan Control:  Fan speed is continuously variable.  
When input voltage is within normal range, the built-
in processor adjusts fan speed according to the 
converter module’s output power.  For example, a 
higher output power increases the fan speed. 

 

Communication Failure:  The protection indicator 
(yellow) will flash should communication between the 
converter module and associated system Controller fail.  
The failure information will be reported to the associated 
system Controller and the Controller will process the 
failure accordingly.  During a communication failure, the 
converter module output voltage will automatically 
adjust to 24.00Vdc.  The converter module will revert to 
normal operation once normal communication is 
restored. 

 

Monitoring Function:  The converter module has a built-
in advanced DSP (Digital Signal Processor) that monitors 
and controls the operation of the converter module.  The 
DSP also communicates with the associated system 
Controller in real time through the CAN bus.  

Table 2

 lists 

the different commands and information exchanged 
between the converter module and the Controller. 

 

External Alarm:  Provided via the associated Controller.  
Refer to the separate Power System documentation for a 
description of available external alarms.
