Test conditions and notes6

1. All parameters NOT specially mentioned are measured at 24,48VDC 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 0.1uf & 47uf 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 http://www.meanwell.com)
5. Strongly recommended that external output capacitance should not exceed 5000uF.
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-30L-5 to power 5V industrial controllers, HMIs, or USB-powered embedded hardware from a higher-voltage DC source?

This model provides a constant 5V output at up to 6A with a 30W power rating. That makes it suitable for 5V control and embedded electronics that stay within 6A. Its 18-72V input range is useful when the source voltage can vary across a wide DC bus.

Is the RSD-30L-5 suitable for 5V single-board computers or industrial communication gateways?

It can be a fit when the device requires a regulated 5V rail and the load does not exceed 6A or 30W. The constant-voltage design is intended for equipment that expects a fixed-voltage supply. Buyers should match the device's required current to the 6A maximum output current.

Can this 5V converter be used in mobile equipment or vibration-heavy automation enclosures?

The features state that it withstands 5G vibration, which supports use in equipment subject to movement or mechanical stress. It also has a -40C to +70C operating temperature range for demanding temperature conditions. The electrical output remains limited to 5V, 6A, and 30W.

Is the RSD-30L-5 rated for outdoor use?

The provided specs list an operating temperature range of -40C to +70C, but they do not list an IP rating. Without an IP rating, the product data here does not confirm outdoor or wet-location suitability. It is more defensible to use it in a protected enclosure unless another enclosure rating is provided.

How does the RSD-30L-5 compare with the other low-power RSD-30L models?

In the RSD-30L family, the RSD-30L-5 is 30W at 5V and 6A, the RSD-30L-12 is 30W at 12V and 2.5A, the RSD-30L-24 is 30W at 24V and 1.25A, and the RSD-30L-3.3 is 19.8W at 3.3V and 6A. The listed dimensions are 113.0 x 60.0 x 25.0 mm for these compact models, with a weight of 0.25 kg. The main selection point is the required output voltage and current.
