Power Supply Components
Colour Description Notes
FUSE Primary AUX Protection.
EMI FILTERS
TRANSFORMER Senses the MAIN’s current
CAPACITOR (4.7 uF)
First Bulk Capacitor
Acts before the PFC
Fast: saves the system from any voltage peak
Low capacitance: should not reduce the ripple
LITTLE CAPACITORS Usually affected by Over-Voltage, which results in the explosion of the nearby Varistor
PRIMARY CAPACITORS
Charges to rectify the MAINS Voltage
Starts the P.F.C. Booster
Capacitors are nally charged to 410 VDC (boost voltage)
3 PARALLEL TRANSFORMERS
A
T1: Manages POWER (1000 W)
B
T2: Manages POWER (1000 W)
C
T3: Manage Power and AUX (1060W), most likely of the three to get broken
SECONDARY CAPACITORS
AUX
BC A
