The  DC  voltages  required  at  various  parts  of  the  chassis  and  panel  are  provided  by  a 
main  power  supply  unit.  MB60  chassis  can  operate  with  IPS60,  IPS16,  IPS17,  PW26, 
PW27 as main power supply and also with 12V adaptor. 

CN706 is used for IPS60, IPS16 and IPS17 and CN1 is used for PW26 and PW27.

JK9 is used for the adapter option and also CN705 inverter socket or DB32 chassis with 
CN706 is used to supply backlight.

The  power  supplies  generate  18V,  12V,  5V,  3,3V  and  12V,  5V,  stand  by  mode  DC 
voltages. Power stage which is on-chassis generates 5V, 3V3 stand by voltage and 12V, 
8V, 5V, 3V3, 2.5V, 1,8V and 1,2V supplies for other different parts of the chassis. Chassis 
block diagram is indicated below.

The  blocks  on  power  block diagram  is  using  dependent  to main  supply.  For  PW26 and 
PW27 just common blocks are enough for proper operation. 

For IPS16, IPS17, IPS60 below blocks must work properly.

For adopter case also below blocks are necessary.
