Power shelf

Mechanical

The power shelf provides housing for plug-in rectifiers and for an optional LVD. The power shelf provides power connections and signal access to the rectifiers.

As listed in Table 4, there are two shelf sizes with the following capacities:

a)19-inch mounting - 2 x MPR25 or MPR15 (Figure 4)

-2 x MPR25 or MPR15 + LVD

-3 x MPR25 or MPR15

b)23-inch mounting - 3 x MPR25 or MPR15 (Figure 5)

-2 x MPR25 or MPR15 + LVD (Figure 7)

-2 x MPR25 or MPR15 + LVD + RPM1000C (Figure 6)

-3 x MPR25 or MPR15 + EQL SW Assembly (Figure 8)

c)There are two main application versions: System

•In the system version (Table 4) the rectifier signals are brought out from the shelf through cables terminated with connectors which connect to the power plant's Controller.

•The AC input is either common bussed or individually fed, equipped or not, for EMI filtering to the rectifiers.
