Test conditions and notes8
- 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 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. 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-65B in an industrial control panel that needs 5V logic and plus/minus 12V analog rails?
Yes. The RT-65B is a triple-output constant-voltage power supply with 5V, 12V, and -12V outputs and 64.6W total power. That makes it a fit for industrial or automation equipment that combines a 5V control rail with plus/minus 12V circuitry in one compact supply.
Is the RT-65B suitable for embedded test equipment with mixed-voltage boards?
It can be a good fit for embedded or lab-style equipment that uses a 5V rail alongside 12V and -12V rails. The unit provides 5A on the 5V output and 64.6W total output power, which suits lower-power mixed-signal assemblies rather than larger loads.
Can the RT-65B be used for automation systems that combine digital control and analog signal conditioning?
Yes, if the system needs constant-voltage outputs at 5V, 12V, and -12V. Its triple-output design is appropriate for automation hardware that uses 5V digital control with bipolar analog sections, and the supply is rated for 64.6W total.
Will the RT-65B fit space-constrained equipment housings?
It is designed as a miniature-size supply and measures 129.0 × 98.0 × 38.0 mm. That footprint can help in compact industrial or embedded assemblies where multiple voltage rails are needed without moving to a larger chassis supply.
Can the RT-65B operate in hot control cabinets or vibration-prone machinery?
The rated operating temperature is -25°C to +70°C, and the listed features include 70°C operation and 5G vibration resistance. Those specs support use in demanding indoor industrial environments where heat and equipment vibration are concerns.
How does the RT-65B compare with nearby RT series models?
The RT-65B is rated at 64.6W with outputs of 5V (5A), 12V (2.8A), and -12V (0.5A). Other models in the RT-65 series include the RT-65A (66.1W, 5V/12V/-5V), RT-65C (65.5W, 5V/15V/-15V), and RT-65D (68W, 5V/24V/12V). Higher power siblings like the RT-125 series offer greater wattage but different voltage combinations.
