Test conditions and notes11

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 0.1uf & 47uf 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 ambient temperature derating of 3.5℃/1000m is needed for operating altitude greater than 2000m(6500ft)
6. The power supply is considered a component which will be installed into a final equipment. 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)
7. Please refer to derating curve.
8. R type efficiency slightly less than the Blank type, according to the actual measurement.
9. Inrush current parameter has 10% tolerance.
10. RCM is on voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1.
11. Some models or factory may not have the BIS marking , please contact MEAN WELL’s sales for more details.

FAQ

Can I use the UHP-500-48 for 48V industrial control or automation equipment?

Yes, if the equipment requires a constant 48VDC input. This supply is rated for 501.6W and 10.45A, so it is intended for 48V automation and control loads within that output range.

Is this power supply suitable for a 48V telecom-style or industrial networking DC bus?

It can be suitable for 48VDC equipment that expects constant voltage input. With 48V output, 10.45A current capacity, and a 90-264VAC input range, it fits higher-power 48V bus applications that stay within 501.6W.

Would the UHP-500-48 work for 48V motion, control, or test systems?

Yes, for systems designed around a constant 48V source. Its 501.6W power rating and 10.45A output make it a fit for 48V industrial benches, controls, and similar electronics that need more capacity than lower-power 48V models.

Can this be used for a 48V LED or display power application?

It can be used when the load is built for constant 48VDC operation and the total demand does not exceed 501.6W or 10.45A. As a constant voltage supply, it is meant for 48V systems rather than constant current lighting applications.

Is the UHP-500-48 okay for indoor enclosures with wide temperature swings?

The specified operating range is -30°C to +70°C, which supports broad indoor temperature conditions. The listed data does not include an IP rating, so exposure to rain, spray, or washdown is not confirmed by the provided specs.

How does the 48V version differ from the other UHP-500 models?

The listed UHP-500 options are 500.4W at 12V and 41.7A, 501W at 15V and 33.4A, 501.6W at 24V and 20.9A, 500.4W at 36V and 13.9A, 501.6W at 48V and 10.45A, 400W at 5V and 80A, and 336W at 4.2V and 80A. This unit is the 48V model, with a lower current rating than the lower-voltage versions because it keeps the output in the 501.6W class.
