EK12/fu c : 03 11.ß~
The Simplatron controller series 490 comprises five 4—quadrant
DC speed controllers with 6.4 to 80 kW output power in compact
design.
1. Special features
-
compact controllers with potential-free heatsink
-
Highly dynamic due to six-pulse three-phase bridge design
and discontinuous current adaptation
—
Isolation due to current transformers
-
Operation by tacho or armature voltage feedback with
IxR compensation
-
Self synchronisation of the phase shifter for 50-60Hz mains
-
High interference margin by built-in synchronizing filters
-
Pulse series firing in the power stage
-
High operational safety due to static and dynamic voltage
