SITOP
SITOP lite
The low-cost basic power supply
The SITOP lite power supplies are designed for standard requirements in industrial environments and offer all
important functions at a favorable price.
The wide range input with manual switchover supports connection to a variety of single-phase supply systems.
Thanks to the slim design, the power supplies have a low space requirement on the standard mounting rail, and
their excellent degree of efficiency ensures low thermal losses in the control cabinet.
Essential product features
• 24 V DC/2.5 A, 5 A and 10 A
• For industrial applications with basic requirements
• Single-phase wide range input with manual switchover
SITOP smart
The powerful standard power supply
SITOP smart are the universal and powerful standard power supplies for machinery and plant engineering.
Despite their compact design, they offer excellent overload behavior:
Thanks to 150 % extra power, loads with high power consumption can be connected without any problems and
the permanent overload capability of 120 % offers power reserves in case of expansions. The high degree of
efficiency results in low energy consumption and minimal heat generation inside the control cabinet.
Essential product features
• 1-phase, 24 V DC/2.5 A, 5 A, 10 A and 20 A as well as 12 V/7 A and 14 A
• 3-phase, 24 V DC/5 A, 10 A, 20 A and 40 A
• Compact design - no lateral installation clearances required
• Extra power with 1.5 times the rated current for 5 s/min for brief overloads
• 120 % of the rated power continuously usable at up to 45 °C ambient temperature (24 V versions)
• 24 V power supply units expandable with add-on modules and DC UPS
• High efficiency up to 91.5 %
SITOP power supplies in SIMATIC design
The optimum supply for the SIMATIC S7 and more
The original power supplies of the SIMATIC ideally fit into the PLC network in terms of design and functionality. In
addition to the SIMATIC controllers S7-1500, S7-300, SIMOTION C and the distributed I/O ET 200MP, ET 200M
and ET 200pro, they also reliably supply other loads with 24 V DC.
SITOP modular
The technology power supply for demanding solutions
SITOP modular offers maximum functionality for use in complex plants and machines. The wide-range input
enables connection to any power system in the world and ensures high safety even in the event of extreme
voltage fluctuations. The Power Boost function briefly supplies up to three times the rated current. And in the event
of an overload there is a choice between constant current with automatic restart or latching disconnection. The
high degree of efficiency keeps energy consumption and heating in the control cabinet low, and the compact
metal housing also saves space.
Essential product features
• 1-phase, 24 V DC/5 A, 10 A, 20 A, 40 A
• 1 and 2-phase, 24 V DC/5 A, 10 A
• 3-phase, 24 V DC/20 A, 40 A, 36 V/13 A and 48 V/10 A, 20 A
• DC/DC converter 24 V DC/20 A for drive and battery networks
• Extremely slim design – no lateral clearances required
• Extra power function for brief operational overloads
• Power boost for tripping protective devices
