Overview
Description
Figure 1 View of devices
SITOP PSU400M is a power supply for DC link voltages of drive systems. If the power fails,
the energy of the flywheel mass and in the DC link capacitors is used to maintain the 24 V
supply for the electronics. As a consequence, axes can be stopped or retracted in a
controlled fashion. This can prevent expensive workpieces from being destroyed.
The key benefits of the product include:
●Rated input voltage 600 V DC
●Operating voltage range 200 (300) - 900 V DC
●High degree of efficiency up to 95 %
●Output voltage can be adjusted in the range 24 - 28.8 V
●Ambient temperature -25 ... 70 °C (derating from 60 °C)
●Brief overload capability of 150% for 5 s/min (extra power)
●No lateral mounting clearances are required
●Selectable short-circuit behavior
●Soft characteristic for parallel switching can be selected
●integrated signaling contact for "24 V O.K."
●Display of the operating state using 3 LEDs

Device description
2.1.1
PSU400M
SITOP PSU400M is a primary-clocked power supply for connection to DC supply voltages
(e.g. to the DC link voltage of drive systems). 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 display indicates the operating
status. The operating state of the device can be processed via the signaling contact.

Voltage rise limiter
The 6EP1566-3AA00 voltage rise limiter is used as ballast for the PSU400M 24 V/20 A
power supply.
A filter is integrated in the ballast to improve the EMC of power supply PSU400M (only
applicable for product version 1).
It is not permissible that a 6EP1566-3AA00 ballast device is connected in parallel or in series
with a second ballast device.

Potentiometer
The potentiometer ④on the front of the device is used to adjust the output voltage. The
output 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.
Figure 2-5 Potentiometer
NOTICE
Thermal overload possible
When adjusting the output voltage to > 24 V, the output current must be derated by 4 %/V,
or the permissible ambient temperature must be taken into account with 3 °C/V.
Note
It is only permissible to use an
insulated screwdriver when actuating the potentiometer.
For notes on actuating the potentiometer (screwdriver, torque), see Chapter Figure 2-3
Terminal data for 6EP1536-3AA00 (Page 11).

influences the output
characteristic
in the load range
Parallel operation:
"Soft" characteristic curve (see Figure 6-7 Out-
put characteristic parallel operation (Page 37))
for the parallel operation of two or more devic-
es: The output voltage falls with increasing
output current (namely, also for the overcurrent
pulse!).
This means that for full output current the high-
est output voltage can normally no longer be
attained.
Single operation:
Delivery state
"Hard" characteristic curve (see Figure 6-6
Output characteristic single operation
(Page 36)) for normal operation (single opera-
tion): The output voltage is independent of the
output current.
B
influences the output
characteristic
in the overload range
Latching shutdown:
If the output current rises above the rated value
and above the current limit, the device reduces
the output voltage (see Figure 6-8 Output char-
acteristic latching shutdown (Page 37)). If the
output voltage falls below 20 V, the 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 cur-
rent' feature is not available in this operating
mode. In order to also be able to charge large
capacitances in this operating mode at the
output, non-latching shutdown is performed
during the first ten seconds after power on.
During these first 10 s, the device responds for
overload as if the switch is "OFF".
Constant current:
Delivery state
If the output current rises above the rated value
and above the current limit, the device reduces
the output voltage. The yellow LED lights up if
the output voltage falls below 20 V.

Selector switches may only be activated when the device is switched off.
