Test conditions and notes10
- 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. (In order to meet tolerance, it is recommended that CH1 load > 15% rated current for A, B,D type and CH1 load > 20% rated current for C type.)
- 4. Line regulation is measured from low line to high line at rated load.
- 5. Load regulation is measured from 20% to 100% rated load, and other output at 60% rated load.
- 6. Each output can work within current range. But total output power can't exceed rated output power.
- 7. 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 )
- 8. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
- 9. Testing harmonic current at 85%load.
- 10. 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 RT-125C for industrial or embedded equipment that needs 5V and ±15V rails?
Yes, this model provides 5V, 15V, and -15V outputs from one unit. That output combination is relevant for embedded and industrial electronics that need both a 5V logic rail and symmetrical 15V rails.
Is the RT-125C suitable for analog signal-conditioning or instrumentation circuits?
It can be a good fit where the electronics need 5V plus 15V and -15V rails. The total power rating is 132.5W, and the 5V output is rated for 10A.
Can the RT-125C support mixed digital and analog boards in one enclosure?
Yes, the output set of 5V, 15V, and -15V is useful when one enclosure contains both logic and analog sections. Its triple-output design reduces the need to source those rails from separate power supplies.
Would the RT-125C work in compact automation hardware that sees vibration and wide indoor temperature variation?
The unit is specified for -25°C to +70°C operation, and the features list includes 5G vibration resistance. Its 199.0 x 98.0 x 38.0 mm dimensions also suit space-conscious industrial hardware builds.
Is the RT-125C intended for outdoor environments?
The temperature range is broad at -25°C to +70°C, but no IP rating is provided in the product data. That means it is best treated as a supply for protected indoor locations or enclosed equipment rather than exposed outdoor use.
How does RT-125C differ from the other RT-125 power supplies?
RT-125C is the 132.5W model with 5V, 15V, and -15V outputs and a 5V current rating of 10A. The other listed RT-125 versions are RT-125A at 131W with 5V, 12V, and -5V, RT-125B at 132W with 5V, 12V, and -12V, and RT-125D at 136W with 5V, 24V, and 12V.
