Overview
The 3-phase SITOP PSU8200 power supply from the SITOP modular product line is a high-
performance, stabilized technology power supply for automated machines and systems.
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..28.8 V
●Power boost during operation with 300% rated current for 25 ms
●Extra-Power with 1.5x rated current for 5 seconds for switching on loads with a high
inrush current
●Especially low width without requiring any lateral mounting clearances
●Ambient temperature -25...+70 °C
●Selectable short-circuit response (constant current or latching shutdown)
●A soft characteristic can be selected for a parallel connection (for uniform load distribution
of power supply units of the same type)
●Display of the operating state using 3 LEDs

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.

2.1
Device description
SITOP PSU8200 3ph 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 displays indicate the operating state. The operating state of the
device can be processed via the signaling contact.

2.3
Potentiometer
The potentiometer ③on 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 ... 28.8 V; for
example, to compensate voltage drops across long supply lines to the connected load.
Figure 2-4 Potentiometer
NOTICE
Thermal overload possible
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.
Note
It is only permissible to use an insulated screwdriver when actuating
the potentiometer.
For notes on actuating the potentiometer (screwdriver, torque), see Figure 2-2 Terminal data

Change-over switch
Figure 2-6 Selector switch
The two switches A and B are used to influence the output characteristic curve:
Switch
ON
OFF
A
influences the output
characteristic in the
load range
Parallel operation:
"Soft" characteristic curve (see Figure 6-5 Output
characteristic curve 6EP3436-8SB00-0AY0 parallel
operation (Page 32) and Figure 6-6 6EP1437-3BA10
parallel operation output characteristic curve
(Page 33)) for the parallel operation of two or more
devices: The output voltage falls with increasing out-
put current (namely, also for the overcurrent pulse!).
This means that for full output current the highest
output voltage can normally no longer be attained.
Single operation:
Delivery state
"Hard" characteristic curve (see Figure 6-
3 Output characteristic curve 6EP3436-
8SB00-0AY0 single operation (Page 32)
and Figure 6-4 6EP1437-3BA10 single
operation output characteristic curve
(Page 32)) for normal operation (single
operation): The output voltage is inde-
pendent of the output current.
B
influences the output
characteristic in the
overload range
Latching shutdown:
If the output current rises above the rated value and
above the current limit, the device reduces the output
voltage (see Figure 6-7 Output characteristic curve
6EP3436-8SB00-0AY0 latching shutdown (Page 33)
and Figure 6-8 6EP1437-3BA10 latching shutdown
output characteristic curve (Page 33)). If the output
voltage falls below 20 V, the device shuts down latch-
ing, the red LED lights up. This limit voltage of 20 V is
independent of the set output voltage. The 'Short-time
overload current' feature is not available in this oper-
ating mode. In order to also be able to charge large
capacitances in this operating mode at the output,
non-latching shutdown is performed during the first
ten seconds after power on. During these first 10 s,
the device responds for overload as if the switch is
OFF.
Constant current:
Delivery state
If the output current rises above the rated
value and above the current limit, the
device reduces the output voltage. The
yellow LED lights up if the output voltage
falls below 20 V.
Delivery state: A-OFF; B-OFF
Note
Selector switches may only be activated when the device is switched off.

WARNING
Installing the device in a housing or a control cabinet
The SITOP PSU8200 3ph 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 according to
EN 60715.
Mounting
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 this is too difficult, press slider
⑧at the same time, as described under "Removal".
Removal
To remove, pull up the slider ⑧using 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.

Standard mounting position
The device is mounted on standard mounting rails according to EN 60715. The device must
be mounted vertically in such a way that the input terminals and the output terminals are at
the bottom to ensure correct cooling.
A clearance of at least 50 mm should be maintained above and below the device (maximum
depth of the cable duct, 50 mm).
No space is required at the side.
