SIMATIC 575 Power Supplies

Description and Ordering Data

NOTE: The backplane termination consumes 1.0 A from the +5 V supply.

The PPX:575-6660 Power

Supply provides up to 185 W

to the VME base. It operates

on 110 VAC input voltage.

The PPX:575-6663 Power

Supply provides up to 300 W

Overview

to the VME base. It operates

on either 110 or 220 VAC

input voltage, depending on

the position of the

user-accessible jumper

selector.

The load power supplied by the +12 or -12 volt output must not exceed the power supplied by the +5 volt output (i.e., with a 5 A load on the +5 V, the load

current supplied by the +12 or -12 must not exceed 2A.

+5 V current draw must be reduced by the amount of the V

stdby

current used.

The battery will maintain memory for a time inversely proportional to the current consumed (e.g. 5Ah / 4 mA = 52 days, assuming a fully charged battery).
