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 PSU8200 1 ph is a primary-clocked power supply for connection to a 1-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 device can be switched ON/OFF
remotely using a remote contact.
SITOP PSU8200 20A 1ph is a primary-clocked power supply for connection to a 1-phase/2phase AC line supply or a DC 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 ③ on 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.
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.
nly permissible to use an insulated screwdriver when actuating the potentiometer.
For information on actuating the potentiometer (screwdriver, torque), see Figure 2-4

characteristic curve 6EP3333-8SB00-0AY0 parallel
operation (Page 42)) for the parallel operation 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 highest
If the output current rises above the rated value and
above the current limit, the device reduces the output
voltage (see, e.g. Figure 6-9 Output characteristic
curve 6EP3333-8SB00-0AY0 latching shutdown
(Page 43)). If the output voltage falls below 20 V, the
device shuts down latching, the red LED lights up.
This limit voltage of 20 V is independent of the set
output voltage. The "Short-term overload current"
feature is not available in this operating mode.
6EP3333-8SB00-0AY0 and 6EP3334-8SB00-0AY0
are reset using power supply OFF for a minimum of
60 s or remote OFF and ON at the remote contact.
6EP1336-3BA10 is reset by switching the power supply OFF for at least 5 s.
To also guarantee that large capacitances can be
charged at the output in this operating mode, a nonlatching shutdown is not performed during the first
10 s after power ON or remote ON. During these first
10 s, the device responds for overload as if the switch
is OFF.

Function: The device is remotely switched off when contacts 15, 16 are short-circuited
(R < 8 kΩ). If the power supply is shut down and latched in the "latching shutdown" mode
as a result of an overload, then it can be restarted using remote OFF followed by remote
ON.
