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-150-12 for a 12V industrial control panel with multiple loads?

Yes, this model is a constant-voltage 12V supply rated for 12.5A and 150W. That makes it suitable for larger control panels, distributed 12V loads, and automation assemblies that need more headroom than small 12V supplies.

Is the RS-150-12 a good choice for 12V CCTV, access control, or alarm hardware?

It can be a fit for centralized 12V security and control hardware when the total demand stays within 12.5A. With 150W available, it supports higher combined 12V loads than compact power supplies in the same series.

Can this power supply run 12V automation peripherals such as relays, controllers, and interface modules?

Yes, it is designed for constant-voltage 12V output and can support multiple 12V automation peripherals on one supply. The practical limit is the unit's 150W maximum output and 12.5A current rating.

Is the RS-150-12 suitable for larger 12V LED or signage systems?

It is often a better fit for larger 12V constant-voltage loads because it provides substantially more output than the lower-wattage 12V RS models. Buyers should size the total load against the published 150W and 12.5A ratings.

Can the RS-150-12 handle demanding indoor environments?

The operating temperature range is -25Β°C to +70Β°C, which is broader than the smaller 15W models in this set. The provided specs do not list an IP rating, so it is best used in protected indoor enclosures rather than directly exposed outdoor environments.

How does the RS-150-12 compare with other 12V RS series models?

The listed 12V siblings are RS-15-12 at 15.6W and 1.3A, RS-25-12 at 25.2W and 2.1A, RS-35-12 at 35W and 3A, RS-50-12 at 50.4W and 4.2A, RS-75-12 at 72W and 6A, RS-100-12 at 102W and 8.5A, and RS-150-12 at 150W and 12.5A. RS-150-12 is the highest-output 12V model listed in this sibling group.
