Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 230VAC 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, when multi-channel output, it is recommended that CH1 load > 10%.
  4. 4. Line regulation is measured from low line to high line at rated load.
  5. 5. Load regulation is measured from 0% to 100% rated load.
  6. 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 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 )
  7. 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 the RT-50A be used in a small industrial control panel that needs multiple DC rails?

Yes. The RT-50A is a triple output constant voltage power supply with 46.5W total power, 5V output listed at 4A, and additional 12V and -5V rails in the model spec. Its 99.0 × 97.0 × 36.0 mm size also suits compact control enclosures where space is limited.

Is the RT-50A a fit for legacy logic or embedded equipment that still uses a negative rail?

It can be a good fit when the equipment needs the specific RT-50A output set of 5V, 12V, and -5V from one supply. The unit is constant voltage, rated for 46.5W total, and provides 5V at 4A on its main listed output. That combination is relevant for older control, embedded, and interface boards that require more than one DC rail.

Can I use the RT-50A for bench testing PLC I/O or automation boards?

It is suitable for low-power bench or cabinet-side testing where the load fits within 46.5W total and the 5V rail stays within 4A. The wide 88-264VAC input is useful if the same supply may be used on different AC mains. Because it is a triple output model, it can support test scenarios that need 5V together with 12V and -5V rails.

Is the RT-50A suitable for harsh factory conditions or outdoor use?

The operating temperature range is -25°C to +70°C, and the features list says it withstands 5G vibration and 70°C operation, which supports use in demanding indoor industrial environments. However, no IP rating is provided in the listed specs. Without an IP rating, outdoor or washdown suitability should not be assumed from this data alone.

How does the RT-50A compare with other RT series models?

The RT-50A is a 50W-class triple output model with 46.5W total power and 5V at 4A. Other models in the RT-50 series include the RT-50B (50W, 5V/12V/-12V), RT-50C (50W, 5V/15V/-15V), and RT-50D (51W, 5V/24V/12V). Higher power options like the RT-65 and RT-125 series are also available in the RT family, offering different voltage combinations and higher current ratings.
