Test conditions and notes7

1. All parameters NOT specially mentioned are measured at △230VAC(Y 400VAC) 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. During withstand voltage and isolation resistance testing, the screw "A" shall be temporarily removed, and shall be installed back after the testing.
5. There is high possibility to trigger the floating over voltage protection when PV voltage is trimmed from a high voltage level to a lower voltage level at light load or no load condition. It is suggested that turn off the power supply and set PV voltage to the lowest level, then adjust output voltage to a desired value.
6. 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 720mm*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)
7. 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 RST-5000-48 for a 48V industrial automation cabinet with high DC load demand?

Yes, this model is a constant-voltage 48V supply rated for 5040W and 105A. That output level fits large 48V industrial automation systems that need substantial DC power from a single power supply.

Is the RST-5000-48 suitable for powering 48V motors, actuators, or other heavy embedded equipment?

It can fit heavy 48V DC equipment because the supply provides 48V at up to 105A with 5040W total power. Buyers should match their equipment to a constant-voltage 48V source and stay within the unit's 105A and 5040W ratings.

Can this power supply be used in a high-power telecom or IT DC system that runs on 48V?

Yes, the electrical profile aligns with high-power 48V DC systems because it delivers 48V constant voltage and up to 105A. Its input range of 196-530VAC also supports deployment in facilities with higher-voltage AC infrastructure.

Is the RST-5000-48 appropriate for scalable 48V systems that may need more than one power supply?

Yes, one of the listed features is active current sharing up to 20000W(3+1). That makes it relevant for larger 48V systems that need power expansion beyond a single 5040W unit.

Can I use the RST-5000-48 outdoors or in harsh temperature conditions?

The operating temperature range is -30°C to +70°C, so it is designed for wide-temperature operation. No IP rating is listed in the provided specs, so it is better treated as a unit for protected enclosures rather than exposed outdoor or wet locations.

How does the RST-5000-48 compare with other Mean Well RST series models?

Within the listed siblings, the 48V options are RST-5000-48 at 5040W and 105A and RST-10000-48 at 10080W and 210A. Other RST models span 24V, 36V, 115V, 230V, and 380V outputs, with power ratings from 4800W up to 15030W and current ratings from 19.77A up to 400A.
