Chopper equipment (VTCI) with microprocessor control system
The chopper equipment (VTCI) drives a DC motor in electrical traction and rheostatic/recuperative brake. The equipment can be controlled with the microprocessor control system SATREC-MMA01. It is designed for trolleybuses driving systems, regardless of line polarity.
