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. 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. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 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 SPV-300-48 for 48V telecom or network power applications?
It can be used where the equipment requires a constant 48V DC source and the total load stays within 300W and 6.25A. That makes it relevant for 48V IT, telecom, and communications hardware designed for a 48V bus.
Is the SPV-300-48 suitable for 48V industrial automation equipment?
Yes, this model provides constant 48V output at up to 6.25A, which fits automation or control equipment built around a 48V DC rail. The 300W rating is useful when multiple 48V loads are fed from one supply.
Can the SPV-300-48 power 48V embedded or lab test systems?
Yes, it is appropriate for 48V embedded platforms, benches, or fixtures that need a regulated constant-voltage source up to 300W. The 88-264VAC input also supports use across a wide AC input range.
Is this a good fit for 48V DC distribution inside equipment cabinets?
It can be, as long as the cabinet loads are designed for constant 48V input and stay within 6.25A and 300W. The built-in active PFC function and PF>0.95 may also matter in higher-power cabinet systems.
Is the SPV-300-48 rated for outdoor environments?
No, the SPV-300-48 is an open-frame unit with no IP rating listed in the specifications. It is designed for indoor use within a protective enclosure and is not suitable for outdoor environments.
