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-150D-12 to step down a 67.2 to 143V DC source for 12V industrial controls?
Yes, this model converts a 67.2 to 143V input to a constant 12V output. With up to 12.5A output current and a 150W rating, it suits 12V control, monitoring, and automation loads that need regulated 12V from a higher-voltage DC bus.
Is the RSD-150D-12 suitable for transportation, battery, or other high-voltage DC systems that need 12V output?
It is designed for a higher input range than the C-series, with 67.2 to 143V input capability and a 12V constant voltage output. That makes it relevant when the available DC source is above the 33.6 to 62.4V range but the downstream equipment still needs 12V at up to 12.5A.
Can this converter power 12V edge devices or industrial communication equipment from a high-voltage DC rail?
It can, provided the source stays within 67.2 to 143V and the 12V load stays within 12.5A and 150W. The compact 189.0 x 77.0 x 36.0 mm form factor also helps where enclosure space is limited.
Is the RSD-150D-12 meant for outdoor use or protected enclosure use?
The operating temperature range is -40°C to +55°C (no derating), extending to +70°C at 60% load by free air convection. The product is specified to withstand 5G vibration. No IP rating is shown, so it is better suited to protected cabinets or enclosed systems than direct outdoor exposure.
What is the difference between the RSD-150D-12 and the other RSD-150D models?
In the RSD-150D family shown here, the 24V version is the RSD-150D-24 at 151.2W, 24V, and 6.3A, while the 5V version is the RSD-150D-5 at 150W, 5V, and 30A. The RSD-150D-12 is 150W, 12V, and 12.5A, so the main selection point is the required output voltage and current.
