Test conditions and notes8
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 2. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
  3. 3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μf & 47μf parallel capacitor.
  4. 4. Tolerance : includes set up tolerance, line regulation and load regulation.
  5. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.
  6. 6. Touch current was measured from primary input to DC output.
  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).
  8. 8. 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 )

FAQ

Can I use the RPS-45-7.5 for 7.5V embedded or industrial electronics?

Yes, this model supplies constant-voltage 7.5V output up to 5.4A, with 40.5W total power available. It fits 7.5V electronics and control hardware that stay within those output limits.

Is the RPS-45-7.5 suitable for a 7.5V HMI, controller, or instrumentation board inside equipment?

It can be used where the equipment specifically requires a regulated 7.5V rail and needs no more than 5.4A. The 40.5W rating is the key sizing limit for the total connected load.

Can this 7.5V power supply be used in compact medical or laboratory devices?

Yes, for internal 7.5V loads within 5.4A and 40.5W. This unit is medical safety approved and features extremely low leakage current, which is useful in medical and lab equipment design.

Is the RPS-45-7.5 a practical choice for small automation enclosures?

It is well suited when both size and output match the project, since the unit measures 76.2 x 50.8 x 24.0 mm and weighs 0.11 kg. The electrical output is fixed at 7.5V constant voltage up to 5.4A.

How does the RPS-45-7.5 compare with the other RPS-45 versions?

In the RPS-45 family, the sibling models are 3.3V at 26.4W and 8A, 5V at 40W and 8A, 12V at 45.6W and 3.8A, 15V at 45W and 3A, 24V at 45.6W and 1.9A, and 48V at 45.1W and 0.94A. The RPS-45-7.5 version is rated at 40.5W with a 7.5V, 5.4A output.

Can the RPS-45-7.5 handle cold or hot environments, and is it suitable for outdoor exposure?

The specified operating temperature range is -30C to +70C, which supports use in a wide range of indoor equipment conditions. No IP rating is listed, so it should be used in protected indoor or enclosed environments rather than exposed outdoor locations.
