Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

Overview
Figure 1 View of units
The 3-phase SITOP PSU300S from the SITOP smart product line is a powerful, regulated
standard power supply for automated machines and systems. In addition to a high efficiency,
these low-profile power supply units have an outstanding overload behavior.
The key benefits of the product include:
●Wide-range input, which allows it to be connected to almost any 3-phase line supply
around the world
●Output voltage can be adjusted in the range 24 - 28 V
●Brief overload capability of 150% for 5 s/min (extra power)
●Continuous overload capability of 120% up to an ambient temperature of 45 °C
●Integrated signaling contact for "24 V O.K."
●No lateral mounting clearances are required
●ambient temperature -25 ... 70 °C
●To increase the system availability, these reliable power supplies can be expanded using
SITOP supplementary modules (redundancy module, selectivity module, buffer module),
as well as SITOP DC-UPS modules.

2.1
Device description
SITOP PSU300S is a primary-clocked power supply for connection to a 3-phase AC line
supply. An electronically regulated DC voltage that can be set via a potentiometer is
available at the output of the device. The output of the device is isolated, no-load proof and
short-circuit proof. The LED display indicates the operating status. The operating state of the
device can be processed via the signaling contact.

Connections and terminal designation
The line input terminals ①can be used to establish the connection to supply voltage. The
output terminals ②are used to connect to the loads to be supplied (see also Section
Installation (Page 31)).
The operating state of the device can be processed via the signaling contact ④(function
and contact rating, see Chapter Status displays and signaling (Page 13)).
