Power Supplies buying guide
What's in this range
- DIN Rail Power Supplies (24V DC) – single-phase and 3-phase units for control panels.
- DC UPS & Buffer Modules – keep 24 V DC loads running through short mains outages.
- Redundancy, Selectivity & DC Converter Modules – redundant supply, channel protection and SINAMICS DCM DC converters.
How to choose
- Output current: add up all 24 V loads and keep about 20 to 30 percent reserve for inrush and future additions.
- Input: single-phase 100-240 V AC, 3-phase 400-500 V AC or a wide-range input depending on the site network.
- Application type: standard control supply, DC UPS for ride-through, or redundancy module for two supplies in parallel.
- Mounting and environment: DIN rail width, operating temperature and derating, and protection class.
Power Supplies questions
How do I size a 24 V DC power supply?
Total the current of all connected loads, then add a reserve. Choose the next standard rating above that figure, for example 10 A or 20 A.
What is the difference between a DC UPS and a buffer module?
A DC UPS module uses a battery to carry the load, often for minutes. A buffer module uses capacitors to bridge outages of a few hundred milliseconds.
Can you supply Siemens SITOP units internationally?
Yes. Stoklink ships worldwide from Turkey under EXW terms. Lead time depends on distributor stock, and bulk quotes are available on request.
