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)

SITOP PSU8200/3800 3ph

General safety instructions

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 PSU8200/3800 3ph 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. Remote control and remote reset are
possible via the remote ON/OFF.

This means that for full output current the highest

WARNING

Installing the device in a housing or a control cabinet

Mounting

Removal

The SITOP PSU8200/3800 3ph power supply is a built-in device. It must be installed in a
housing or control cabinet, to which only qualified personnel have access.

The device can be mounted in a control cabinet on standard mounting rails (see Chapter
Mechanical system (Page 80))

To mount the device, position it with the mounting rail guide at the upper edge of the
standard mounting rail and press down to lock it into place. If it is too difficult to snap them
into place, press slider at the same time, as described under "Removal".

To remove, pull up the slider using a screwdriver and disengage the device at the bottom
edge of the standard mounting rail. Then you can remove the device from the upper edge of
the standard mounting rail.

WARNING

Use in hazardous zones

If the devices are to be used in hazardous zones (Ex II 3G Ex nA nC IIC T4 Gc) they must
be installed in a distribution box with degree of protection IP54 or higher.

Standard mounting position

Output current as a function of the ambient temperature and mounting height

The device is mounted on standard mounting rails. The device must be mounted vertically in
such a way that the input terminals and the output terminals are at the bottom to ensure
correct cooling.

A clearance of at least 40 mm or 50 mm should be maintained above and below the device
(maximum depth of the cable duct, 50 mm).

No space is required at the side.
