Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

Overview
1-phase SITOP PSU8200 power supplies from the SITOP modular product line are high-
performance, regulated technology power supplies for automated systems and machines.
The key benefits of the product include:
●Suitable for connecting to almost any 1-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 via 3 LEDs
●"DC O.K." signaling contact

●Remote "ON/OFF" contact for switching the power supply unit output into a no-current
state
●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.

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 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.
