Properties of the load power supply
The table below shows a comparison of the various load power supply units and their
properties:
Table 7- 2 Features of load power supply units
Necessary for ... Property of the load power supplies Note
Modules that must be supplied with
voltages of ≤ 60 V DC or
≤ 250 V AC.
24 V DC load circuits
Safe electrical isolation The Siemens power supplies from the
PM 170W and SITOP series have this
feature.
24 V DC load circuits
48 V DC load circuits
60 V DC load circuits
Output voltage tolerances:
