24V Power Supply in IP67 Protection Rating
This rugged new power supply is designed for distributed
use in three-phase networks and supplies 8 A rated output current. It can be
operated in ambient temperatures ranging from -25 to +55°C and is available
in two versions: The SIMATIC ET200pro PS supplies the electronic/encoder and
load voltages for the system components and features a special connector for
looping through the input voltage, in contrast to the otherwise structurally
identical SITOP PSU300P. It can also be used for other applications outside the
control cabinet.

SITOP Power Supplies – Selectivity in 24 V Load
Feeders
The SITOP PSE200U selectivity module distributes the load
current over 4 current circuits and reliably monitors them for overload and short-circuits.
A faulty 24-V feeder is de-energized and the remaining loads continue to be supplied
without interruption, so total failure of the plant is avoided. The fault is
output via a common signaling contact and indicated by an LED on the affected
feeder. Compared to the predecessor device SITOP select, the SITOP PSE200U offers,
for example, remote reset, a reset button for each channel, and a sealable cover
for protecting the output current settings.

First Maintenance-Free DC-UPS with IP65 Rating
The new uninterruptible 24 V power supply with highly-capacitive
capacitors as the energy storage device is now also available with IP65 protection
rating. It can therefore be used outside of the control cabinet at ambient temperatures
of up to +55 °C. The 10 kWs SITOP UPS500P version supplies 7 A output current
at 24 V DC and is suitable for mounting on support arm systems such as required
when using SIMATIC Panel PCs.

Compact 24 V Power Supplies, 20 A and 40 A Units
The innovated 3-phase SITOP PSU300M power supply units
provide a high degree of functionality and performance in just a small space.
With a width of only 70 and 150 mm, the 20 A and 40 A stabilized power supply
units are among the most compact in their performance class. A signaling contact
for evaluating the operating status "24 V DC ok" has been integrated.
The wide input range of 320 to 575 V, the high degree of efficiency up to 93%
and a generous reserve capacity make it possible to use the unit for almost any
application on power networks around the world.
