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 1ph 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.

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.

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 6-7 Output characteristic
curve 6EP3333-8SB00-0AY0 latching shutdown

device shuts down latching, 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 operating mode.
Turning the power supply off for at least 60 seconds
or a remote OFF and ON on the remote contact
causes a reset (only with 6EP3333-8SB00-0AY0 and
6EP3334-8SB00-0AY0).
To also guarantee the upload of large capacitances at
the output in this operating mode, a non-latching
shutdown is performed during the first 10 seconds
after power on or remote ON. During these first ten
seconds, the device responds for overload as if the
