SITOP smart
The high-performance standard power
supply for 1 and 3-phase networks
SITOP smart is the high-performance standard power
supply for automated machinery and plants with 24 V or
12 V DC electronics. Thanks to its high overload capability, even loads with high power demand can be connected
without difficulty. The 24 V power supplies can continuously manage 120% of the rated power. Thanks to their
slim design and seamless installation next to laterally
mounting devices, the power supplies require little space
on the DIN rail. The high degree of efficiency ensures low
energy consumption and minimal heat loss in the control
cabinet.
The flexible input voltage ranges allow problem-free
connection to 1 and 3-phase networks around the world.
Comprehensive certifications also facilitate universal
usage, e.g in hazardous areas.
To further increase the availability, the reliable power
supplies can be combined with DC UPS, redundancy and
selectivity modules.
The benefits at a glance
• Minimum mounting space required due to slim
design, no lateral installation clearances required
• "Extra Power" with 1.5 times the rated current for
5 s/min for brief overloads
• Can be continuously used with 120% of the
rated power at up to 45 °C ambient temperature
(24 V versions)
• Signaling contact for "output voltage OK" for easy
integration in the plant monitoring system
• Low energy consumption and minimal heat dissipation inside the control cabinet due to the high
degree of efficiency
• PSU100S:
automatic range switchover 120/230 V AC
PSU300S:
Wide-range input 400 – 500 V 3 AC
• Adjustable output voltage for compensating
voltage drops
• Wide temperature range from -10 to +70 °C
• Numerous certifications for all standard applications worldwide
Answers for industry.
