Siemens SITOP Industrial Power Supplies for Automation
Siemens SITOP power supplies set the benchmark for reliability in industrial automation. They are engineered for control cabinets where power failure cannot be tolerated: continuous manufacturing lines, CNC machine tools, pumping stations, and SIMATIC controller architectures. The Chastotnik.ua catalog features Siemens models in 24 V and 48 V DC outputs with standard DIN-rail TS-35 mounting.
To ensure uninterrupted uptime, Siemens offers supplementary components alongside primary stabilized power units: redundancy modules, selectivity modules, and buffer units designed to isolate faults and absorb transient loads.

Application & Features
SITOP lite (PSU100L)
2.5 A – 10 A (24 V)
DIN-rail
Cost-effective reliable power supplies for standard automation cabinets.
SITOP smart (PSU100S / PSU300S)
2.5 A – 20 A (24 V / 12 V)
DIN-rail
Compact units featuring 150% overload capacity for inrush current handling.
SITOP modular (PSU8200)
5 A – 40 A (24 V / 48 V)
DIN-rail
Premium power supplies with up to 95% efficiency, 300% Power Boost, and remote diagnostics.
SIMATIC Design (PM1207 / PM1507)
2.5 A – 8 A (24 V)
DIN-rail
Matching form factor for seamless installation alongside SIMATIC S7-1200 and S7-1500 PLCs.
Redundancy Modules (PSE202U / RED1200)
10 A – 40 A
DIN-rail
For coupling two power supplies in a fault-tolerant 1+1 redundant configuration.
When selecting a power unit for industrial automation, calculate steady-state PLC loads separately from electromechanical actuators, contactor coils, and solenoid valves. The SITOP smart and modular series absorb high inrush peaks effortlessly through Extra-Power capability without voltage dips on the controller bus.

Frequently Asked Questions
What are the key differences between Siemens SITOP lite, smart, and modular series?
SITOP lite provides core power functionality for steady-state loads at an economical price point. SITOP smart offers 150% extra power for inrush currents in a slim body. SITOP modular delivers top-tier performance with up to 95% efficiency, 300% Power Boost, and comprehensive diagnostic signaling.
Can Siemens SITOP units power non-Siemens automation hardware?
Yes, Siemens SITOP power supplies deliver stabilized 24 V DC compliant with global industrial standards. They operate reliably with third-party PLCs, HMIs, sensors, and relays from any manufacturer.
Why is a redundancy module (such as PSE202U or RED1200) necessary?
A redundancy module isolates two power supplies connected in parallel using diodes or active MOSFETs. If one unit fails or suffers an AC loss, the load switches to the backup unit seamlessly without CPU shutdown.
Which power supply matches the SIMATIC S7-1200 controller?
The SIMATIC PM1207 or compact SITOP compact / lite 1.3 A, 2.5 A, and 5 A models (such as 6EP1331-5BA10, 6EP1332-1LB00, or 6EP1333-1LB00) are designed specifically for S7-1200 dimensions and power profiles.
Do Siemens SITOP units include built-in short circuit protection?
Yes, all SITOP power supplies include electronic short-circuit protection with automatic restart (hiccup mode or constant current) and overtemperature shutdown.
