Consequences when incorrectly connected to
the line supply:
1) Another supply, e.g. UPS:
S
Defective DC link electrolytic capacitors at
the power supply
S
The following burn:
–
DC link de–coupling diodes
–
PC board tracks of the power supply
Note:
3) L
for 5 kW and 10 kW integrated, therefore not necessary here!
