3.12  Power Supply Management 

3.12.1 Maximum Current Capacity 

The CIE maximum current capacity is 5A. This includes the total current supplied to the main control 
board,  battery  charger,  main  display  board,  expansion  control  boards  and  the  expansion  display 
boards.  

WARNING: The maximum CIE current capacity shall not be exceeded in any applications. 
Otherwise the fuses on the control board may blow and damage the CIE hardware. 

3.12.2 Mains power supply 

The  CIE  mains  power  supply  requirements  are  shown  in  Table  34.    The  maximum  supply  current 
excludes the current drawn by the MDH and the audio amplifier if used.

The  output  voltage  of  the  AC/DC  power  supply  needs  to  be  checked  and  calibrated.  An  on-site 
calibration  may  be  necessary  to  compensate  the  load  variations.  The  calibration  procedure  is  as 
follows. 

 

Use a calibrated and certified multimeter to measure the voltage of the battery terminals. 

 

At the  same  time,  adjust the  AC/DC  power  supply  potentiometer  until  the multimeter  reading 
stabilises between 27.3 

– 27.5V

DC

 on the battery terminals (without connecting the batteries).

 

 WARNING: Care must be taken when adjusting the AC/DC power supply. Do not to touch the 
covered 240V

AC

 wirings and terminals. Do not remove the plastic protection cover unless 

necessary. 

3.12.3 Power supply monitoring 

The CIE constantly monitors the mains power supply and the battery charger voltage.  The CIE power 
supply monitoring characteristics are listed below.
