FAQ

Can I use the SE-450-36 for a 36V industrial motion or automation subsystem?

Yes, if the subsystem is designed for constant voltage 36V DC and its load stays within 12.5A and 450W. That makes it suitable for industrial or automation equipment built around a 36V DC power rail.

Is the SE-450-36 suitable for 36V control equipment in a machine cabinet?

It can be used for 36V control equipment when the total demand does not exceed 12.5A or 450W. The fixed 36V constant voltage output is intended for devices specified for a regulated 36V source.

Can the SE-450-36 power a 36V embedded or industrial communications assembly?

Yes, where the assembly is built for 36V DC input and falls within the 12.5A, 450W output limit. The switch-selectable 90-132VAC / 180-264VAC input can also simplify deployment across different AC supply conditions.

Can the SE-450-36 be used in outdoor or washdown environments?

The operating temperature is listed as -10°C to +60°C, which defines the temperature range in the provided specs. No IP rating is listed, so the product information supports indoor or protected use rather than exposed outdoor or washdown environments.

What is the difference between the SE-450-36 and the rest of the SE-450 family?

The SE-450 family includes 3.3V at 75A and 247.5W, 5V at 75A and 375W, 12V at 37.5A and 450W, 15V at 30A and 450W, 24V at 18.8A and 451.2W, 36V at 12.5A and 450W, and 48V at 9.4A and 451.2W. The SE-450-36 is the 36V version, rated for 12.5A output.
