NOTES
The converter has a single-phase Graezt rectifier bridge supplied with an RC protection filter and a circuit with an excitation loss relay. The three series, TPy3-415/440-…-4B, TPy3-500/520-…-4B and TPy3-660/700-…-4B are different only for the maximum power supply voltage on the power section. The regulation sections have no differences. The converters up to the 650A size have a compact structure while bigger sizes consists of a power and a regulation section connected via a connector cable. Starting from the 110A size, the converters are force-ventilated. It is possible to put up to four option “y” cards on the rear side of the converter's regulator card internally via a flat cable and a FA …connector.
