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 PSU300M/300B 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. The PSU300B devices are optimized to
charge batteries.

2.3
Potentiometer
The potentiometer ④on the front of the device is used to adjust the output voltage. The
output voltage is set to 12 V, 24 V or 48 V in the factory, and can be adjusted in the range
12 ... 14 V, 24 ... 28.8 V or 42 ... 56 V; for example, to compensate voltage drops across long
supply lines to the connected load.
Figure 2-4 Potentiometer (example 6EP1456-3BA00 / 6EP1437-3BA20)
NOTICE
Thermal overload possible
When adjusting the output voltage to >24 V (>48 V), the output current must be derated by
4 %/V or the permissible ambient temperature must be taken into account with 3 K/V
(applies to PSU300M devices).
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
for 6EP1436-3BA10, 6EP1456-3BA00, 6EP1424-3BA00, 6EP1436-3BA20 (Page 10) and

Change-over switch
Figure 2-6 Selector switch (example 6EP1456-3BA00 / 6EP1437-3BA20)
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, e.g. Figure 6-8
6EP1436-3BA10 parallel operation output char-
acteristic curve (Page 46)) for the parallel oper-
ation of two or more devices: The output
voltage falls with increasing output current
(namely, also for the overcurrent pulse!).
This means that for full output current the high-
est output voltage can normally no longer be
attained.
Single operation:
Delivery state
'Hard' characteristic curve (see, e.g. Figure 6-3
6EP1436-3BA10 single operation output char-
acteristic curve (Page 44)) 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, e.g. Figure 6-13
6EP1436-3BA10 latching shutdown output
characteristic curve (Page 48)). If the output
voltage falls below (10 V), (20 V), (40 V), the
device shuts down latching, the red LED lights.
This limit voltage of (10 V), (20 V), (40 V) is
independent of the set output voltage. The
'Short-time overload current' feature is not
available in this operating 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 sec-
onds 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 if the
output voltage falls below
(10 V), (20 V), (40 V).
Delivery state: A-OFF; B-OFF
