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. 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 pin5,6) 0 ~ 0.8V or short.
  7. 7. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: HRPG-150-3.3/-5/-7.5/-12/-15)
  8. 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 HRPG-150-48 for 48V telecom or industrial communication equipment?

It can be used for 48V equipment that needs constant voltage output and stays within 158.4W and 3.3A. That fits lower-power 48V systems better than higher-current 48V loads.

Is the HRPG-150-48 suitable for 48V automation devices or embedded control hardware?

Yes, for 48V automation or embedded hardware that is designed for a fixed 48V DC supply and draws no more than 3.3A. Its rated output is 158.4W at 48V.

Can this model power a small 48V control subsystem in a rack or cabinet?

It is appropriate for a small 48V subsystem if the combined load remains under 3.3A and 158.4W. The 38 mm unit height may also help where vertical space is limited.

How do I check if this 48V power supply is large enough for my load?

Compare your total 48V demand with the supply's 3.3A and 158.4W output rating. If the load exceeds either number, you need a higher-capacity 48V model.

Is the HRPG-150-48 intended for outdoor use or only protected locations?

The temperature specification is -40°C to +70°C, so it is rated for a wide operating temperature range. The provided specs do not include an IP rating, so outdoor sealing or water resistance is not specified.
