Frequently Asked Questions

Can I use the RS-150-3.3 for 3.3V logic and processor rails in industrial electronics?

It is a constant-voltage 3.3V supply rated for up to 30A and 99W. That makes it appropriate for 3.3V industrial electronics loads that need high current at a low voltage.

Is the RS-150-3.3 suitable for powering multiple 3.3V embedded boards from one supply?

Yes, if the combined 3.3V load stays within 30A and 99W. Its constant-voltage output is aimed at systems that require a regulated 3.3V bus.

Can this model power 3.3V communication or control hardware in an automation enclosure?

It can support 3.3V automation hardware that needs a shared low-voltage rail with up to 30A available. The 88-264VAC input also helps when the AC source varies across common mains ranges.

How do I know if the RS-150-3.3 is large enough for my 3.3V load?

Check that your equipment requires constant-voltage 3.3V and that total demand does not exceed 30A or 99W. If your load is above either of those limits, this model is undersized.

Can the RS-150-3.3 be used in hot or cold environments?

The specified operating range is -25°C to +70°C, and the features call out 70°C operation and 5G vibration resistance. No IP rating is provided in the specs, so weather or washdown exposure is not established here.

How does the RS-150-3.3 compare with the other RS-150 versions?

The RS-150 family includes RS-150-12 at 150W, 12V, 12.5A; RS-150-15 at 150W, 15V, 10A; RS-150-24 at 156W, 24V, 6.5A; RS-150-3.3 at 99W, 3.3V, 30A; RS-150-48 at 158.4W, 48V, 3.3A; and RS-150-5 at 130W, 5V, 26A. Compared with the others, the 3.3V version has the lowest voltage and the highest listed current.

Does the job. Wish the terminals were a touch bigger.
