Test conditions and notes6

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.
4. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. 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 )
6. 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 HRP-300N-48 for a 48V industrial control cabinet?

Yes, this model is a constant-voltage 48V supply rated for 336W and 7A, which fits 48V control and automation loads that need a fixed DC output. It accepts 85-264VAC input, so it can be used in installations that need a wide AC input range.

Is the HRP-300N-48 suitable for 48V telecom or network equipment that needs AC-to-DC conversion?

It can be a fit for 48V equipment when the load requires a constant 48V output and stays within 7A and 336W. The wide 85-264VAC input range also makes it suitable where mains input conditions vary.

Can this 48V power supply run embedded or automation test benches?

It is appropriate for 48V embedded or automation benches when the system needs a constant-voltage source and the total draw does not exceed 336W or 7A. The compact 199.0 x 105.0 x 41.0 mm size can also help where panel space is limited.

Can the HRP-300N-48 be used in outdoor or harsh-temperature environments?

The listed operating temperature range is -40°C to +70°C, with output derating at higher ambient temperatures per the derating curve. The provided specs do not list an IP rating, so dust and water exposure suitability is not established by the product data here.
