Main circuit components
Rectifier unit
3500, 4500: 60 A/ 1600 V
5500: 100 A/ 1600 V
Rectifier unit
35 A/ 600 V
Varistor
550 V
Primary choke
The primary rectifier VG101 rectifies the net voltage. The primary choke L001 limits the in-
rush current during switching and filters the DC-voltage together with the smoothing capacitors.
