BOARD FUNCTION:
this card contains all the power components necessary for complete inverter and PFC group.
All the components, three Isotop for PFC stage and one module IMS(Insulated Metal Substrate) for inverter stage ensure total
ground isolation with coolers and reduced EMI disturbances. The PFC stage control the Vbus status at 375vdc. The inverter is Zero
Voltage Switching type with current regulation made by Phase Shifting. Vbus reference and the main transformer current are con-
trolled from analog card 15.14.419 that isolated and derate the signal in order to transmit relative value to digital card 15.14.415
and this one back to inverter and pfc group. A DC capacitors link is present.
LOCATION:
central left side. Electrically speaking it is connect between the main power transformer and receive the power from
input inductance.
DISMANTLING NOTE:
remove screws on power components and cables from input stage and transformer, ref. to following photos
sequence. Pay attention on dismounting and assembling to the right connection of winding from input stage and to pass trough
the TA one of the two transformer leads. It’s recommended lead mark for properly assembling. The flat cables need to be removed
since rack pcb 15.14.419-415,remain otherwise fixed on inverter groupt. Remove also CN6.
The dismantling could be easier removing the bottom aluminium part.
NOTE:
it is supply as kit togheter with power module just soldered on it and separately additional Isotop. Pay attention on dismount-
ing and assembling to the right connection of leads from input stage and to pass trough the TA one of the two transformer leads.
The power components are assembled on heat skin with use of thermic grease(thermic composed). Pcb. or power components not
available separately.
