1 Features of the 480 series of controllers
The 480 series of controllers comprises five fully-controlled two-
quadant controllers with output powers from 10 kW to 115 kW. The
most important features include:
• Compact controllers with isolated heatsink
• High response thanks to six-pulse three-phase bridge and
leakage current adaptation
• Operation with tacho or armature voltage feedback with "I · R
compensation"
• Isolation of control electronics and power stage when tacho
feedback is used
• Self-synchronization of the phase shifter for
50...60-Hz mains
• Mains connection independent of the phase sequence
• High interference margin due to integrated synchronizing filter
• Burst-gate thyristor control in the power stage
• Reliable operation also for mains voltage fluctuations and short-
term mains failures due to static and dynamic voltage
monitoring
• Display of the operating states using LEDs
• Option board can be retrofitted:
− Set-value integrator 2003
− Winding calculator 1071
• Compliance with the CE directives for the erection of a CE
conform drive system
