Test conditions and notes7
- 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. No load power consumption<0.5W when RC- & RC+ (CN100 pin4,6) 0 ~ 8V or short.
- 7. 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 MSP-300-48 for 48V telecom or network-style equipment?
Yes, if the equipment requires a regulated 48V constant voltage source and stays within 336W and 7A. This model is built for 48V DC loads rather than lower-voltage control rails.
Is the MSP-300-48 suitable for 48V industrial control or automation systems?
It can be used where the system is designed for 48V DC input and the total load does not exceed 336W and 7A. The constant voltage output is the critical match for 48V equipment.
Can this model power a 48V embedded platform or communications enclosure?
Yes, provided the platform needs regulated 48V DC and remains within the 336W, 7A rating. It also accepts 85-264VAC input, which supports deployment across a wide AC input range.
Is the MSP-300-48 rated for outdoor temperature exposure?
The listed operating temperature range is -40°C to +70°C, with output derating required per the datasheet's derating curve, which defines its temperature capability. No IP rating is shown in the provided specs, so weather or washdown protection is not established by this data.
How does the MSP-300-48 differ from the other MSP-300 power supplies?
Across the MSP-300 range, the models are MSP-300-3.3 at 198W, 3.3V, 60A; MSP-300-5 at 300W, 5V, 60A; MSP-300-7.5 at 300W, 7.5V, 40A; MSP-300-12 at 324W, 12V, 27A; MSP-300-15 at 330W, 15V, 22A; MSP-300-24 at 336W, 24V, 14A; MSP-300-36 at 324W, 36V, 9A; and MSP-300-48 at 336W, 48V, 7A. This version provides the highest output voltage in the MSP-300 subgroup and the lowest corresponding output current.
