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-300-48 for a 48V industrial or automation system?

Yes, this is a constant voltage 48V power supply rated for up to 7A and 336W. It is suitable for 48V industrial or automation loads that remain within those stated output limits.

Is the HRPG-300-48 appropriate for OEM equipment that distributes 48V DC internally?

It can be used where the equipment is designed around a 48V DC bus and needs a fixed-voltage supply. The maximum available output is 7A, with total output power rated at 336W.

Would this supply fit a shallow control enclosure or low-height rack area?

The housing measures 199.0 x 105.0 x 41.0 mm, so the unit is only 41 mm high. That makes it practical for compact enclosure layouts that still need a 48V DC source.

Can the HRPG-300-48 be used in IT or network-adjacent systems that require 48V DC?

It can be considered for systems that specify a constant 48V DC input and stay within 7A or 336W. The 85-264VAC input range also supports use across a wide range of AC source conditions.

Is the HRPG-300-48 suitable for indoor or outdoor environments?

The unit is specified for operation from -40°C to +70°C, with output derating required at higher ambient temperatures according to the derating curve. No IP rating is listed in the supplied specs, so outdoor exposure is not established by this product data and a protected enclosure should be assumed if the environment is not indoor.

How does the HRPG-300-48 compare with other HRPG-300 output versions?

In the HRPG-300 series, the available outputs are 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 highest-voltage standard HRPG-300 option in that list and one of the two 336W variants.
