Test conditions and notes6

1. All parameters NOT specially mentioned are measured at 24,48,110VDC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. 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 “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
5. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSD-150-5/-12)
6. 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 RSD-150C-12 to power a 12V industrial control cabinet from a 33.6 to 62.4V source?

Yes, this model is a constant voltage DC-DC converter with a 12V output and up to 12.5A output current. That makes it suitable for 12V control electronics that need regulated 12V power within its 150W listed power rating and 33.6 to 62.4V input range.

Is the RSD-150C-12 a fit for 12V mobile or embedded equipment running on a 33.6 to 62.4V DC bus?

It can fit embedded or mobile systems that need a regulated 12V rail and draw up to 12.5A. Its compact 189.0 x 77.0 x 36.0 mm size, 0.8 kg weight, and 5G vibration resistance are relevant where space and mechanical stress matter.

Can this converter support 12V industrial networking or monitoring devices from a higher-voltage DC system?

It is intended for converting a 33.6 to 62.4V input to a constant 12V output. With 12.5A available, it is appropriate for grouped 12V networking, monitoring, or automation loads that stay within the unit's rated output.

Is the RSD-150C-12 suitable for outdoor or harsh-environment enclosures?

It has an operating temperature range of -40°C to +55°C (no derating) and is specified to withstand 5G vibration, so it is designed for demanding conditions. No IP rating is listed, so it is better suited to protected enclosures than direct outdoor exposure.

How does the RSD-150C-12 compare with the other RSD-150C output options?

Within the RSD-150C group shown here, the 5V version is the RSD-150C-5 at 150W, 5V, and 30A, while the 24V version is the RSD-150C-24 at 151.2W, 24V, and 6.3A. This RSD-150C-12 is listed at 150W, 12V, and 12.5A, so the main differences are the output voltage, current, and listed power.
