Series Overview
Series Overview
SDR is a higher performance DIN-rail power supply series, covering common power ranges from 120W to 960W, suitable for industrial control cabinets and applications with higher requirements for power density/dynamic capabilities.
Part-number Structure & Selection Notes
The model structure is SDR-[power]-[output voltage]. The same power series may have different output voltage versions, and the output current and peak capabilities are confirmed according to the corresponding SPEC. SDR is a mature series with a large installed base and should be retained alongside the new generation of XDR products.

FAQ
Frequently Asked Questions
How do I confirm the complete part number for SDR DIN-rail power supply?
The model structure is SDR-[power]-[output voltage]. The same power series may have different output voltage versions, and the output current and peak capabilities are confirmed according to the corresponding SPEC. SDR is a mature series with a large installed base and should be retained alongside the new generation of XDR products.
What are the main differences between SDR-120-24 and SDR-240-24?
power class: SDR-120-24 is 120W, SDR-240-24 is 240W. Verify the complete ordering code and project conditions before selection or replacement; the series name alone is not sufficient.
Which specifications matter most when selecting SDR DIN-rail power supply?
Key specifications to verify are output voltage, power class. Match them against the equipment nameplate, drawing or original model, and retain every suffix, option and regional code in the complete ordering reference.
Why is the complete part number required when requesting a quote for SDR DIN-rail power supply?
Models within SDR DIN-rail power supply may differ in electrical ratings, construction, interfaces or accessories. For example, SDR-120-24, SDR-240-24, SDR-480-24 are distinct configurations and cannot be interchanged on the series name alone. Using the complete part number substantially reduces mismatch risk.
