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-150-5 for 5V industrial electronics with high current draw?

Yes, if the equipment needs a constant 5V supply and the total demand stays within 26A and 130W. That makes it suitable for low-voltage industrial loads that need much higher current than smaller 5V supplies.

Is the RS-150-5 a good fit for powering multiple 5V embedded controllers from one source?

It can support a shared 5V rail for multiple embedded devices as long as the combined load does not exceed 26A or 130W. Its constant-voltage output is intended for equipment designed around a regulated 5V input.

Can this model support 5V automation hardware in a control cabinet?

It is appropriate for 5V automation hardware that requires a constant-voltage bus and stays within 26A. The wide 88-264VAC input also helps when the same design is used across different AC supply ranges.

How do I size the RS-150-5 for a 5V load?

Match it to equipment that requires constant-voltage 5V, then total the current and power demand. This unit is rated for 26A and 130W, so the connected load needs to remain at or below both figures.

Can the RS-150-5 be used where ambient temperatures swing widely?

The operating temperature range is -25Β°C to +70Β°C, and the feature list includes 70Β°C operation with 5G vibration resistance. No IP rating is listed in the provided specs, so indoor versus outdoor exposure is not defined here.

How does the RS-150-5 compare with the other RS-150 models?

The listed RS-150 versions are 12V at 12.5A and 150W, 15V at 10A and 150W, 24V at 6.5A and 156W, 3.3V at 30A and 99W, 48V at 3.3A and 158.4W, and 5V at 26A and 130W. The 5V model is the high-current option between the 3.3V version at 30A and the 12V version at 12.5A.
