Test conditions and notes7
- 1. All parameters NOT specially mentioned are measured at 230VAC 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, when multi-channel output, it is recommended that CH1 load > 10%.
- 4. Line regulation is measured from low line to high line at rated load.
- 5. Load regulation is measured from 0% to 100% rated load.
- 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. 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-50C be used for industrial electronics that need both positive and negative 15V rails?
Yes, if the equipment matches the RT-50C's triple output arrangement of 5V, 15V, and -15V. The supply is rated for 50W total and provides 5V at 4A on its main listed output. That makes it more relevant for analog control and signal-processing hardware than a single-output supply.
Is the RT-50C appropriate for embedded test fixtures with logic and analog sections?
It can be a fit when the fixture needs a constant voltage source and the total load remains within 50W. The main listed output is 5V at 4A, and the model spec also includes 15V and -15V rails. That combination is useful where digital logic and analog support rails need to come from one power supply.
Can I use the RT-50C in a small instrumentation cabinet?
Yes, for lower-power instrumentation loads that fit within the 50W total rating. Its compact dimensions of 99.0 × 97.0 × 36.0 mm and weight of 0.41 kg help in tighter cabinet layouts. The 88-264VAC input also supports broad AC input compatibility.
Is the RT-50C rated for outdoor service or only for controlled enclosures?
The provided specs show an operating temperature range of -25°C to +70°C and note 5G vibration resistance, which supports demanding indoor equipment use. However, no IP rating is listed. Based on the provided data, outdoor exposure should not be assumed.
How does the RT-50C sit within the RT family lineup?
The RT-50C is a 50W triple-output model providing 5V at 4A, 15V at 1.5A, and -15V at 0.5A. It features universal AC input (88-264VAC), 76% typical efficiency, and free air convection cooling. The unit measures 99x97x36mm and includes protections for overload and overvoltage, with a 3-year warranty.
