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.
  4. 4. 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 )
  5. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.
  6. 6. No load power consumption<0.5W when RC- & RC+ (CN100 pin4,6) 0 ~ 0.8V or short.
  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 I use the HRPG-300-3.3 for a high-current 3.3V embedded or logic rail?

Yes, this model is built for constant voltage output at 3.3V and can deliver up to 60A. Its 198W rating makes it relevant for embedded or digital systems that need substantial current at a very low DC voltage.

Is the HRPG-300-3.3 suitable for powering 3.3V industrial electronics in one cabinet?

It can be a fit where multiple 3.3V loads are combined on one regulated DC source. The total demand still needs to stay within the published 60A output current and 198W power rating.

Would this power supply work for 3.3V test fixtures or burn-in stations?

It can work in fixture or test environments that need a constant 3.3V supply with high available current. The wide 85-264VAC input is also useful when the equipment may be deployed in different AC input regions.

Is the HRPG-300-3.3 a good option where a low-profile high-current DC supply is needed?

This unit measures 199.0 x 105.0 x 41.0 mm, a height of only 41 mm. That can help in dense industrial or embedded builds where 3.3V at up to 60A is required without moving to a larger chassis format.

Can the HRPG-300-3.3 be used outdoors or in wide-temperature environments?

The operating temperature range is listed as -40°C to +70°C, with output derating required at higher ambient temperatures according to the derating curve. No IP rating appears in the provided specs, so outdoor exposure is not confirmed by this listing and a protected enclosure should be assumed for non-indoor use.

How does the HRPG-300-3.3 compare with other HRPG-300 models?

The HRPG-300 series includes 198W at 3.3V and 60A, 300W at 5V and 60A, 300W at 7.5V and 40A, 324W at 12V and 27A, 330W at 15V and 22A, 336W at 24V and 14A, 324W at 36V and 9A, and 336W at 48V and 7A. This model is the lowest-voltage option in that set and one of the highest-current entries at 60A.
