FAQ

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.
