Electrical specifications of the power shelves
Each rectifier position provides interconnection points for AC input, DC
output and control and alarm signals.
The total output capacity for each shelf is 75 amperes for the MPS75
power shelf and150 amperes for the MPS150 power shelf.
The MPS75 is available in two versions:
• One that provides for common AC feed for the three rectifiers.
• One that provides for individual AC feed for each of the three
rectifiers.
