Frequently Asked Questions

Can I use the RPS-400-18 for an 18V medical or laboratory instrument?

Yes, if the instrument requires a constant 18V DC supply and the load stays within 13.9A and 250.2W. This model is medical approved and intended for equipment needing regulated 18V output rather than a lower-voltage rail.

Is this power supply suitable for 18V industrial automation equipment?

It can be used with industrial automation or control equipment that is designed for 18V constant-voltage input. The available output is 13.9A at 18V, and the input range is 80-264VAC.

Can the RPS-400-18 support an 18V imaging, sensing, or embedded platform?

It is a practical option for embedded or sensing platforms that run from an 18V bus and need more headroom than smaller 18V supplies. With 250.2W available, it fits higher-power 18V loads as long as the total current does not exceed 13.9A.

Would this work for an 18V bench or rack-mounted electronics system?

Yes, when the system is built around 18V DC and the total draw remains within the 250.2W rating. The compact 127.0 x 76.2 x 35.0 mm form factor can be useful where board area and height are limited.

Is the RPS-400-18 meant for indoor or outdoor use?

The specified operating temperature is -30C to +70C, but no IP rating is provided. Without a listed IP rating, it is generally better suited to indoor equipment or protected housings than to exposed outdoor environments.

How does the RPS-400-18 compare with other 18V options in the RPS line?

For 18V output, the listed siblings are RPS-400-18-C, RPS-400-18-SF, and RPS-400-18-TF at the same 250.2W and 13.9A, plus RPS-500-18 at 320.4W and 17.8A, RPS-500-18-C at 309.6W and 17.2A, and RPS-500-18-SF and RPS-500-18-TF at 500.4W and 27.8A. This places the RPS-400-18 in the 250.2W, 13.9A tier below the higher-output 500-series 18V models.
