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.

WARNING
Correct handling of the devices
When operating electrical devices, it is inevitable that certain components will carry
dangerous voltages.
Therefore, failure to handle the units properly can result in death or serious physical injury
as well as extensive property damage.
Only appropriately qualified personnel may work on or in the vicinity of this equipment.
Perfect, safe, and reliable operation of this equipment is dependent on proper
transportation, storage, installation and mounting.
Before installation or maintenance work can begin, the system's main switch must be
switched off and measures taken to prevent it being switched on again.
If this instruction is not observed, touching live parts can result in death or serious injury.

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.

Potentiometer
NOTICE
Thermal overload possible
Note
It is only permissible to use an insulated screwdriver when actuating the potentiometer.
2.3 Potentiometer
The potentiometer ③ at the front of the device is used to adjust the output voltage. The
output voltage is set to 24 V in the factory, and can be adjusted in the range 24 - 28 V; for
example, to compensate voltage drops across long supply lines to the connected load.
Figure 2-5 Potentiometer (example 6EP1437-2BA20)
When adjusting the output voltage to >24 V, the output current must be derated by 4 %/V,
or the permissible ambient temperature must be taken into account with 3 °C/V.
For notes on actuating the potentiometer (screwdriver, torque), see Figure 2-2 Terminal data
for 6EP1433-2BA20 and 6EP1434-2BA20 (Page 10), Figure 2-3 Terminal data for 6EP14362BA10 (Page 10) and Figure 2-4 Terminal data for 6EP1437-2BA20 (Page 11)

WARNING
Installing the device in a housing or a control cabinet
Mounting
Removing
The SITOP PSU300S power supply is a built-in device. It must be installed in a housing or
control cabinet, to which only qualified personnel have access.
The device can be mounted in a control cabinet on standard mounting rails (see Chapter
Mechanical system (Page 44))
To mount the device, position it with the mounting rail guide at the upper edge of the
standard mounting rail and press down to lock it into place. If it is too difficult to snap the
device into place, press the slider at the same time, as described under "Removal".
To remove, pull up the slider using a screwdriver and disengage the device at the bottom
edge of the standard mounting rail. Then you can remove the device from the upper edge of
the standard mounting rail.
