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-24 for 24V PLC or industrial I/O systems on a 67.2 to 143V DC source?

Yes, it provides a constant 24V output from a 67.2 to 143V input range. With 6.3A output current and a 151.2W rating, it fits regulated 24V automation loads within that power range.

Is the RSD-150D-24 appropriate for 24V monitoring, control, or communications hardware on higher-voltage DC buses?

It is intended for applications where the source voltage is in the 67.2 to 143V range but the equipment needs a stable 24V output. The 24V constant voltage design and 6.3A capacity make it relevant for many industrial electronics and control subsystems.

Can this model be used in compact mobile or vehicle-based 24V control assemblies?

It can be a fit where the input voltage matches 67.2 to 143V and the load requires 24V at up to 6.3A. The 189.0 x 77.0 x 36.0 mm dimensions, 0.8 kg weight, and 5G vibration specification are useful in space-constrained equipment exposed to motion.

How well does the RSD-150D-24 handle temperature extremes or exposed conditions?

The unit is rated for -40°C to +55°C operation with no derating, and up to +70°C at 60% load by free air convection. Because no IP rating is listed, it is best used in protected enclosures rather than directly exposed outdoor locations.

How does the RSD-150D-24 compare with the 5V and 12V versions in the same family?

The RSD-150D-24 is rated at 151.2W with a 24V output and 6.3A output current. In the same RSD-150D range, the RSD-150D-12 is 150W, 12V, and 12.5A, while the RSD-150D-5 is 150W, 5V, and 30A.
