Test conditions and notes10
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1ΞΌF & 47ΞΌF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Line regulation is measured from low line to high line at rated load.
  5. 5. Load regulation is measured from 0% to 100% rated load.
  6. 6. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to β€œEMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  7. 7. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
  8. 8. Extra consideration should be taken when selecting output wiring for 3.3V and 5V models. This is to prevent the protection modes for overload and short circuit from becoming constant power.
  9. 9. Testing harmonic current at 80% load.
  10. 10.The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

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 -25Β°C to +70Β°C, and the features call out 70Β°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.
