Should I select a switching supply by watts or voltage?
Match output voltage first, then size power from continuous load, startup current and environment. Both conditions are essential.

The metal-enclosed SFY-Z range provides confirmed 240W, 300W, 360W and 480W ratings with 12V, 24V, 36V and 48V output choices. Selection must consider continuous load, startup current, cooling, mounting space and operating environment together.
The load voltage must match the supply output. The range offers DC 12V, 24V, 36V and 48V options.
List steady power, startup current and recurring peaks, then apply a margin appropriate to the application.
The listed operating range is -10°C to +50°C. Verify airflow and any derating for enclosure temperature, altitude and site conditions.
The catalogue lists overcurrent, overvoltage, short-circuit and over-temperature protection. Confirm model-specific compliance before ordering.
Match output voltage first, then size power from continuous load, startup current and environment. Both conditions are essential.
The confirmed range covers 240W, 300W, 360W and 480W.
Evaluate temperature, cooling, input and load profile and apply an appropriate project margin rather than selecting by nameplate power alone.
Provide input, output voltage/current, continuous and peak load, mounting space, environment, compliance needs, quantity and application.
