Test conditions and notes7
  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. 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-75-12 for a 12V automation device or industrial control accessory?

Yes, this is a 12V constant-voltage power supply rated for 72W and 6A. It fits 12V automation or control loads that stay within those output limits.

Is the RS-75-12 suitable for a 12V CCTV, access control, or monitoring device?

It can be, provided the equipment needs 12V constant voltage and the total draw does not exceed 6A or 72W. Those ratings make it more suitable for medium 12V loads than smaller 12V adapters.

Would this model work for a 12V control panel with several low-voltage devices?

Yes, if all connected 12V devices together remain within 6A and 72W. Its open-frame size of 129.0 x 98.0 x 38.0 mm is also relevant when fitting it into a panel layout.

Can the RS-75-12 be used in machinery that sees vibration?

The product features specify 5G vibration resistance, which is useful in industrial equipment. The application still needs to match its 12V constant-voltage output and 6A maximum current.

Is the RS-75-12 meant for outdoor installations or wide temperature ranges?

Its operating temperature is rated from -25C to +70C, which supports demanding indoor temperature conditions. No IP rating is listed in the provided specs, so outdoor use should not be assumed.
