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

Overview
The 3-phase power supply from the SITOP PSU8200 product line is the powerful, regulated
technology power supply for automated machines and systems.
The 3-phase power supply from the PSU3800 product line is the power supply optimized for
charging batteries.
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
●The output voltage can be adjusted in the range 12 - 14 V/24 - 28 (28.8) V/36 - 42 V/
42 - 56 V
●Power boost during operation with 300% rated current for 25 ms (only PSU8200)
●Extra-Power with 1.5x rated current for 5 seconds for switching on loads with a high
inrush current (only PSU8200)
●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)
●3 LEDs are used to display the operating state
●Signaling contact "12 V O.K"/"24 V O.K"/"36 V O.K"/"48 V O.K"

●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
●The properties of the PSU3800 power supplies makes them ideal for battery charging
