Product Overview
The Siemens 6EP3437-8SB00-0AY0
is a SITOP PSU8200 stabilized industrial
power supply designed to provide a regulated
DC voltage for industrial control and automation
equipment. This power supply operates from a
three-phase AC input with a rated
input voltage of 400–500V AC and
supplies a rated 24V DC output at 40A.
The nominal output power is
960W, calculated from the rated
output voltage and current.
The manufacturer specifies a wide permissible
AC input voltage range of
320–575V AC, allowing the supply
to accommodate variations within the defined
input range.
The output voltage is adjustable from
24V to 28V DC, subject to
the manufacturer's maximum output power
limit of 960W.
Siemens specifies an output voltage tolerance
of 3%, line regulation of
0.1%, and load regulation
of 0.2%.
As part of the SITOP PSU8200 product family,
the module is intended for stabilized
24V DC power distribution in industrial
automation and electrical control systems.
It can be considered for compatible control
cabinet installations, industrial machinery
and automation equipment requiring
a regulated 24V DC power source.
The exact incoming supply network,
operating load, wiring, installation
protection and output power requirements
should be checked before installation.
This is specifically a
3-phase AC 400–500V input version
and must not be confused with Siemens
single-phase SITOP power supplies or
other voltage and current variants.

production state PS:3,
and Made in Romania.
Packaging identity has been verified
against the requested Siemens order number.
The physical power supply nameplate
should be confirmed before dispatch.
