5.1 Description of the design
5.1.1
The supply module consists of:
•
Main switch
•
Main fuses
•
Control fuses
•
Residual current circuit breaker, 3-phase
•
Main contactor
•
3-phase AC constant-voltage transformer 0 – 710V, motor operated
•
3-phase AC rectifier
The module is used for provision and distribution of the voltages and currents required
for the system. The system may provide maximum 2 A current of both AC and DC.
5.1.2
The signal generator comprises:
•
Motor controlled AC transformer with a adjustment range of 0 – 230 V
•
Rectifier
•
Change-over contactors/relays for 1-ph AC/3-ph AC and DC.
.
The system may provide maximum 1A current of both AC and DC voltage.
It is used to provided the required control voltage in the three current types mentioned.
5.1.3
Connection of the various power inputs/outputs
This unit implements the connections required using power contactors.
