For regulating inductive and ohmic consumers.
The main area of ??application is the stepless speed control and / or torque control of DC motors up to an output of 640 watts in straight-ahead drive without braking. Reverse operation with braking is possible using the armature switchover relay circuits C-AU-12 (option surcharge).
Compact single-board device with plug-in terminal connection or as a plug-in device in 3HE with 10TE front panel and VG connector strip. The control electronics consist of a slope limiter (integrator), speed controller (RVU), current controller (RVI) and ignition device. The power section is made of fully insulated power semiconductors, the heat sink is potential free. The underside of the device is protected by a fully insulated plastic frame with plug-in terminals.
