Test conditions and notes9

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 and Static characteristics for more details.
5. PV/PC functions when users do not use SVR.
6. Output will shut down after O/P voltage is below < 80% of Vset for 5 sec, re-power on to recover.
7. 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 1100mm*650mm 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)
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).
9. Please contact MEAN WELL technical staff to confirm that the product and the water-cooling system match the relevant specifications.

FAQ

Can I use the UHP-2500-48 for a 48V telecom or industrial communications power system?

Yes, this is a constant-voltage 48V model rated for 2500.8W and 52.1A. That makes it relevant for 48V DC systems used in telecom, communications, and industrial control environments that require a high-power 48V source.

Is the UHP-2500-48 a fit for 48V automation equipment or large control panels?

It can be a fit where the equipment is designed for 48V constant-voltage input and the total load stays within 2500.8W and 52.1A. The 310 × 140 × 60 mm slim profile also suits larger control-panel layouts where space planning matters.

Can this model support a 48V embedded platform or DC bus in industrial equipment?

Yes, the unit is built around a 48V constant-voltage output with up to 52.1A available. That output class is commonly considered for embedded industrial platforms and centralized 48V DC buses that need more power than smaller 48V supplies provide.

Can the UHP-2500-48 be used in cold or hot operating conditions?

The specified operating temperature range is -30°C to +70°C, which supports use across a broad temperature span. No IP rating is listed, so environmental sealing for outdoor or exposed locations is not established by the provided specs.

What are the differences between the UHP-2500-24, UHP-2500-36, and UHP-2500-48?

The UHP-2500-24 is rated for 2500.8W at 24V and 104.2A, the UHP-2500-36 is rated for 2498.4W at 36V and 69.4A, and the UHP-2500-48 is rated for 2500.8W at 48V and 52.1A. They are all in the same slim, fanless UHP-2500 class, with the key difference being output voltage and resulting current.
