Test conditions and notes6
  1. 1. All parameters NOT specially mentioned are measured at 24,48,110VDC 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 0.1μF & 47μF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 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. 5. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSD-150-5/-12)
  6. 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-24 for 24V PLC, relay, or automation loads on a 33.6 to 62.4V DC system?

Yes, it provides a constant 24V output with up to 6.3A output current from a 33.6 to 62.4V input range. That fits 24V automation loads that need regulated 24V and stay within the 151.2W rating.

Is the RSD-150C-24 appropriate for 24V HMI or industrial communications equipment?

It is a constant voltage converter with a 24V output and 6.3A available current. That makes it a practical choice for 24V industrial electronics and communications devices powered from a higher-voltage DC source in its specified input range.

Can this model be used in battery-based or vehicle-mounted 24V control systems?

It is designed to convert 33.6 to 62.4V input power down to a regulated 24V output. The 189.0 x 77.0 x 36.0 mm housing, 0.8 kg weight, and 5G vibration specification support use in compact systems exposed to movement or vibration.

Does the RSD-150C-24 work for outdoor cabinets or only indoor enclosures?

The unit is rated for operation from -40°C to +55°C with no derating, and up to +70°C at 60% load by free air convection. No IP rating is given, so it is better matched to sheltered cabinets or other protected enclosures rather than exposed outdoor mounting.

What is the difference between the RSD-150C-24 and the other RSD-150C voltage versions?

In the same RSD-150C group, the RSD-150C-5 is 150W, 5V, and 30A, while the RSD-150C-12 is 150W, 12V, and 12.5A. The RSD-150C-24 is 151.2W, 24V, and 6.3A, so the choice comes down to required output voltage and current.
