2.3.2 Functional Description
Power Module:
The power module consists of an input rectifier, soft start facility for the current-limited loading of the
intermediate circuit, the IGBT power semiconductor with free-wheeling diode and over voltage
protection.
The average value of the output voltage is always positive. The output is current-limited and thus short-
circuit-proof.
Control and Monitoring:
The voltage regulator UNITROL 1000-15 does the communication between machine and excitation
systems. In this unit all machine data is set, feedbacks processed and the necessary parameters
adjusted. For the power module no special parameters are to be adjusted in the voltage regulator. The
transmission of the control signals to the power module is made by CAN Bus.
Alarm output:
A potential free relay contact is available.
LED display:
Five LED' s inform about the operating condition of the unit. See description in section 2.3.5.
